The Seedor Bitcoin B: A Precision Bitcoin Metal Stamp for Serious Cold Storage

Most seed backup tools are sold by people who have never secured a wallet. This bitcoin metal stamp is different: built by bitcoiners, specced openly, and designed to work with the Seedor holder jig that keeps every strike vertical and every impression clean.

What Is the Seedor Bitcoin B: Your Bitcoin Metal Stamp for Cold Storage

The Seedor Bitcoin B is a 6 x 6 x 60 mm punch tool machined from drawn 40CR tool steel. It carries the Bitcoin B logo at a 3.5 mm font height. CryptoCloaks sized it specifically for the Seedor alignment system, which means the 6 mm shank fits the holder channel and every strike lands at 90 degrees to the backup surface.

A bitcoin metal stamp needs to do one thing well: transfer a clean, readable impression to your backup surface without slipping, drifting, or leaving a ghost mark. The Seedor Bitcoin B does exactly that. The 40CR steel is hard enough to mark stainless plates, leather, and plastics without deforming the tip, and tough enough to take repeated hammer blows without losing geometry.

This is not a generic crypto tool with an unverified steel spec and a coin logo. It is a Bitcoin-specific stamp, built to Bitcoin standards, sold by a shop that has been in the space since 2017. If you are building a cold-storage backup meant to last decades, this is the mark that belongs on it.

Why CryptoCloaks

CryptoCloaks has been in the Bitcoin space since 2017. Ricky personally picks, prints, and ships every order from his shop in America. That accountability matters when you are buying a tool you will use to protect generational wealth. There is no warehouse, no dropship chain, no anonymous marketplace seller behind this bitcoin metal stamp.

The stamp ships as part of a complete ecosystem. The Seedor stamp holder for vertical alignment keeps every punch perpendicular to the surface during a strike. Reddit threads on DIY metal stamping consistently name misaligned strikes as the top failure mode. A tilted stamp leaves a partial, unreadable impression. The holder eliminates that variable before it becomes a problem.

Additionally, CryptoCloaks publishes its specs openly. You know the steel grade. You know the font height. You know the shank dimensions. Generic marketplace listings cannot say the same. That transparency is a direct expression of the Bitcoin ethos: verify, do not trust.

Bitcoin Metal Stamp Specs and Compatibility

• Dimensions: 6 x 6 x 60 mm
• Font height: 3.5 mm
• Material: Drawn 40CR tool steel
• Weight: 3 oz
• Compatible surfaces: Metal plates, leather, plastics
• Compatible jig: Seedor holder system
• SKU: CC-SD-SEEDBITCB

Steel grade matters more than most buyers realize when selecting a bitcoin metal stamp. Jameson Lopp’s metal Bitcoin seed storage stress test validates drawn tool steel in the 40CR hardness range as capable of leaving legible impressions in stainless steel plates under severe fire, crush, and corrosion conditions. A soft stamp deforms at the tip. A brittle stamp chips. Drawn 40CR holds its geometry through thousands of strikes, keeping the Bitcoin B crisp on every backup you make.

The 3.5 mm font height fits standard seed plate grids without crowding adjacent characters. The 60 mm handle provides a controlled grip surface during a hammer strike. At 3 oz, this bitcoin metal stamp is light enough for precise positioning and solid enough to feel intentional in hand.

Frequently Asked Questions

Can I use this stamp to punch my Bitcoin seed phrase into a metal plate?

The Seedor Bitcoin B is a bitcoin metal stamp designed to mark the Bitcoin B logo, not individual BIP39 seed words. For a complete seed phrase backup, you pair this stamp with a set of letter and number punches sized to the Seedor grid. The Bitcoin B stamp serves as a clear identifier on your backup plate, marking it as a Bitcoin wallet backup rather than a generic document. That distinction matters in an emergency, when someone else may need to locate and use your backup quickly. The 40CR steel punches cleanly into standard stainless steel plates, titanium sheets, and aluminum backups at the thicknesses most cold-storage products use. Plan one deliberate strike per surface position and use the Seedor holder to keep every mark aligned.

What surface should I stamp on to get the cleanest impression?

This bitcoin metal stamp is compatible with metal plates, leather, and plastics. For long-term seed backups, stainless steel or titanium plates produce the most durable and legible impressions. Place a firm, flat backing under your plate before striking. A single deliberate hammer blow at full arm weight gives cleaner results than a series of lighter taps. Avoid any surface with flex or give beneath the plate, because movement mid-strike causes the stamp to drag and leaves a partial impression. For practice runs before committing to your real backup plate, use a scrap piece of aluminum or a leather offcut. Both take clean marks at moderate strike force, allowing you to dial in your technique without risking your actual backup material.

Does this stamp work with the Seedor alignment holder / jig?

Yes. CryptoCloaks designed this bitcoin metal stamp specifically for the Seedor holder system. The 6 x 6 mm shank profile fits the Seedor jig channel, which holds the stamp at exactly 90 degrees to the backup surface during a strike. That vertical alignment is the single most important factor in getting a clean, full-depth impression. Without a holder, even experienced stampers tilt the punch slightly on impact, leaving a partial mark on one edge. The Seedor holder removes that variable entirely. If you are serious about building a readable, durable seed backup, pairing this stamp with the Seedor holder is the correct approach. It is not an optional upgrade, it is the system working as designed.

Add the Seedor Bitcoin B to your cold-storage toolkit today. It is the bitcoin metal stamp built with published steel specs, a jig-compatible design, and nearly a decade of Bitcoin-native community trust behind every order. Bitcoin accepted. Made in America. Ships in 2-3 business days.

Stamping a seed phrase onto metal is not the place for guesswork, and a jig that gives you only 12 index positions leaves too much room for crooked letters and costly mistakes. The CryptoCloaks 1 Inch Washer Stamping Jig gives you 16 precisely indexed positions around the full circumference of a standard 1-inch washer, so every character lands exactly where you intend it.

What Is the CryptoCloaks 1 Inch Washer Stamping Jig

A washer stamping jig is a small positioning tool that holds a metal washer firmly in place while you strike letter or number punches into its face. Without a jig, each punch lands wherever your eye and hammer decide, which means uneven spacing, slanted characters, and a finished backup that looks (and reads) like a mess. The jig solves that problem by giving you a fixed seat for the washer and a series of indexed notches or holes that tell you exactly where to set the punch before each strike.

This jig is designed for standard 1-inch outer-diameter washers, which is the most widely used size in the bitcoin seed backup community. The 16 indexed marking spots are spaced evenly around the full 360-degree circumference, giving you more placement options than the original BlockMIT design and enough positions to stamp a full BIP39 word list abbreviation on a single washer face without running characters together. The tool ships flat, measures 3 x 3 x 0.25 inches, and weighs 2.7 ounces, so it adds almost nothing to your kit.

The jig is compatible with a standard 1/8-inch (3mm) square engraving punch, the same punch size used by most dedicated seed-stamping sets on the market. If you already own a punch set for metal stamping, there is a very good chance you can put this jig to work today without buying any additional tooling. If you are building your stamping kit from scratch, pairing this jig with a set of 3mm square punches and a set of 1 inch stainless steel washers for seed stamping gives you everything you need to create a durable, fire-resistant, corrosion-resistant bitcoin seed backup.

Why CryptoCloaks

CryptoCloaks has been operating as a bitcoin-native shop since 2017. Ricky, the founder, personally picks, prints, and ships every order from his shop in America. That is not marketing copy. It means when you have a question about your order, you are talking to the person who made it. It means quality control does not get outsourced to a fulfillment warehouse. And it means that the verified 5-star reviews attached to this product come from real people who have used this specific jig to stamp real seed phrases, not from reviewers who received a generic product shipped from an anonymous marketplace listing.

The jig is available in 17 colors: Black, Cherry Red, Red, Orange, Yellow, White, Florescent Green, Green, Dark Green, Dark Blue, Blue, Clear, Beige, Bronze, Silver, Purple, and Pink. That range is not just cosmetic. Color-coding your backup tools is a legitimate organizational strategy when you are managing wallets across multiple hardware signers or maintaining separate backups for different purposes. Picking a dedicated color for each backup context takes 10 seconds and eliminates the risk of grabbing the wrong jig mid-process.

Stamping mistakes happen. A mis-strike and you break the jig. That is why the backup bundle option exists. For $4.99 you get two jigs instead of one. That is $1.98 per jig, If you break a jig you got a spare! No competitor listing on eBay or Etsy offers a comparable bundle with this kind of pricing transparency.

Metal seed backups are one of the most reliable ways to protect a bitcoin wallet against loss from fire, water, or hardware failure. If you are new to the process, the Bitcoin Foundation’s guide on how to securely back up your Bitcoin wallet is a solid starting point before you pick up a punch set. Once you understand what you are protecting and why, the physical stamping process becomes straightforward, and having a precision jig like this one removes the last variable that turns a careful backup into a sloppy one.

Frequently Asked Questions

What size washers fit the CryptoCloaks 1 inch stamping jig?

This jig is designed to seat standard 1-inch outer-diameter (25.4mm) washers securely, and it also accommodates 24mm washers. These are the most common washer sizes used in the bitcoin seed backup community because they offer enough surface area to stamp a meaningful amount of text while remaining compact enough to store easily. Hardware store washers in this size range are widely available in stainless steel, which resists corrosion and holds up well under heat. If you want to skip the hardware store trip, CryptoCloaks sells purpose-made stainless steel washers sized specifically for this jig. When sourcing washers independently, confirm the outer diameter before purchasing because washers labeled as “1 inch” can vary slightly between manufacturers and may not seat correctly in the jig if they run oversized.

Do I need a special punch set to use this jig, and what size punch does it take?

The jig is designed for a standard 1/8-inch (3mm) square engraving punch, which is the most common punch size sold in dedicated bitcoin and crypto seed-stamping kits. If you already own a stamping kit for metal work, check the punch tip size first. Round punches can also work in some cases, but square-tipped punches produce cleaner, more legible characters on metal washers because the flat edges create sharper lines. You do not need any specialty bitcoin-branded tooling. A basic 3mm letter and number punch set available from most tool suppliers pairs directly with this jig. The key is consistency: use the same punch depth and hammer weight for each strike, and the 16 index positions on this jig will keep your characters aligned without any additional guesswork.

Why does the bundle come with two jigs instead of one?

Because stamping a seed phrase onto metal is a process where mistakes happen, and when they do, having a second jig ready matters more than you expect. The jig itself is not consumable, but it is a small 3D printed part that can crack or warp if a heavy hammer strike misses the punch and lands on the tool directly. Simply have a spare on hand without waiting on a reorder. At $4.99 for the pair, you are paying $1.98 per jig. It is the most sensible way to buy this tool if you are taking your seed backup process seriously, and no comparable bundle option exists on eBay or Etsy for this product category.

Order the CryptoCloaks 1 Inch Washer Stamping Jig today and get a precision seed phrase stamping tool built by a bitcoin-native shop that has been in the space since 2017.
