Durable Knife Spine Protector or Improved Compact Ferro Rod Striker.
The user's knife (a Jääkäripuukko 110, with an 80CrV2 steel spine) got damaged when striking a firesteel. This is a common issue, as many knife spines aren't hardened enough for this task, leading to damage. Meanwhile, the dedicated strikers that come with firesteels are often small, ineffective (like a couple of inches chopped off a hacksaw blade), and easily lost, which is a frequent frustration. This presents an opportunity for either:
-
A precision-engineered, attachable spine guard made from hardened steel (e.g., appropriately heat-treated tool steel or high-carbon steel). This guard would have a dedicated, sharp 90-degree striking edge and be designed to securely attach to the spines of popular outdoor knife models using a non-marring mechanism (like a lined friction-fit or robust clip). This solution would protect the knife's softer spine while still allowing the user to use the knife as the handle for striking.
-
An improved, ergonomic, and highly durable dedicated ferro rod striker. This would feature a comfortable, secure-grip handle (e.g., G10 or textured polymer, possibly in bright, high-visibility colors), an ultra-durable and highly effective striking element (such as multi-edged hardened steel or a tungsten carbide insert), and significantly improved loss-prevention features like a prominent lanyard hole for robust cordage, addressing the common issue of users losing their strikers.
Expected benefit: To prevent damage to users' knife spines (like the "rolled over" edges on softer steels like 80CrV2) during fire starting, and to offer reliable, convenient, and highly effective fire-starting solutions. This can be achieved either by enabling safe use of the knife itself via a protective striking attachment or by providing a superior, ergonomic, and hard-to-lose dedicated striker, thereby enhancing the preparedness and experience of outdoor and survival enthusiasts.

Firesteel destroying the spine of my Jääkäripuukko 110. Is this normal?
Posted by u/gnzo•06/05/2025
Freshly filed spine rolled over after just 3 strikes

If you don't want to damage your spine then use the metal tool designed for it on your Firesteel
u/Basehound
I might add … if you used a grinder to create or clean up the 90 degree spine , you may have gotten it too hot and ruined the temper .
u/gnzo
I usually just use the Striker that came with the ferrorod but wanted to try and found it curious that the spine degrades so fast. I think it is 80CrV2 Steel.
u/Wojtkie
That’s what we would use in Boy Scouts. Worked great
u/Von_Lehmann
Its 80crv2, which is a tough steel but not the hardest. Honestly I never understood why people use their knives to strike a firesteel when it comes with a specific tool for it
u/reaper_boegh
I usually use my knife but occasionally use my leatherman saw. That spine is sharp enough to cut yourself on and throws a massive shower of sparks

Old files work incredibly well as well. Can even take one and turn it into a knife. Now you have a knife, fire rod striker, pry bar, and (if you leave the rasps) something to help process som

Not every spine is hardened. A hardened spine makes the knife more brittle.
I think striking a firesteel on the back of your knife is a bit overrated. Strikers are small and most firesteels
u/Rabid-Wendigo
This is why i use the striker that comes with my bar. I don’t want to damage tge hard edge or the soft spine of my knife unnecessarily

What is that, 420HC steel? Maybe use something else that doesn’t take so much pressure to throw sparks.

Because they saw it in a YouTube video and it looks cool. Because in a survival situation, you throw away the tools you have with you and use only your knife. Because.

Exactly this, just get a Victorinox Farmer or even a Hiker as a companion. The spine on the Vic saws work great too

It’s not on their website anymore, but the description used to mention something about how they sandwich a harder core of steel between two softer layers. So the middle where the actual edge

What brand is that from the title, I expected to see terava but that isn't one.

I like using the saw on my leatherman actually. But I usually just tie a loop of para on the striker and the ferro rod so I have them together, I just find it so much easier to control

Light my fire firesteel comes with a striker use that instead.

Soft metal & or temper. I looked at the specs & wasn't impressed by those. Put it this way, I ordered my knife from the USA with a +20% import tax & £20 postage to the UK when fin

It's softer on the spine, the blade itself is much harder. That's how they do their knives, which are absolutely a steal for the money, im very impressed with my skrama, the edge takes a long

Unless you know the relative hardnesses of the two materials...... not all knives are the same and not all firesteels are the same. To create sparks, material is consumed. Good knives usually

If you don't want to damage your spine then use the striker designed for it on your Firesteel

I usually just use the Striker that came with the ferrorod but wanted to try and found it curious that the spine degrades so fast. I think it is 80CrV2 Steel.
u/Rabid-Wendigo
This is why i use the striker that comes with my bar. I don’t want to damage tge hard edge or the soft spine of my knife unnecessarily

Plus, you have a couple inches of hacksaw blade to cut a groove if you need.

Because they saw it in a YouTube video and it looks cool. Because in a survival situation, you throw away the tools you have with you and use only your knife. Because.
