Steel: The “welding steel” at Tractor Supply/ Lowes/ Home Depot is mild steel and useless for knives Buy new, known, annealed blade steel. It is well worth it. Files, railroad spikes, lawnmower blades and other unknown steels can definitely be used for practice forging but will not perform for a knife. For the work involved, it is very cheap to buy and use known good steel.

Quenchants for Oil hardening steel

Forget the Goddard's Goop Quench, Motor Oil, Transmission Fluid

Use commercial quench oil & match oil speed to the steel type Here is a good post by Kevin Cashen with the Explanation and classification of oil speeds

For heat treating yourself with minimal equipment, find a Eutectoid steel 1080, 1084. Grocery store canola oil can work well -if you use clean preheated oil

Brine and water are cheap for "water hardening" steels W1 and 1095, but use fast oils Parks 50 & Houghton Quench K If you use water or brine, expect broken blades!

Calculating bevel angle.

I'm about to get grinding on a Serbian chef knife & need some assistance in calculating my bevel angle.

Stock is 3.3mm thick Desired height of bevel is 25mm & 38mm

How do I calculate what my angles would be at those heights? I've looked around & couldn't find a formula for this specific issue.

Thank you.

Ribbed Handle

I need help, I’m kind of new and I was wondering what is the most efficient way to make a ribbed handle like seen in the picture with the ribs going down the length of it. My first thought was a lathe but I don’t have one so I was wondering if there was some trick to it.

Safe Sword Cane?

An elderly family friend of mine hates that he needs a cane now. He is a vet and a knife nut like myself. so for his b-day I bought him a cheap sword cane, under estimating how much he would like it.
Rather than just keeping it around the house he tried to use it as he everyday cane.
Unfortunately the thing broke and he almost suffered a fall, Which of course made me feel Very guilty for not double checking that he understood it wasn't meant to replace his actual cane. And for buying him something cheaper than what he seemed to think.

Which leads me to my question, How would y'all recommend I find an artist who Makes sword canes that aren't the equivalent of gas station pocket knives?
Google these days doesn't seem to show me anything but mass produced Temu stuff. And Etsy is frankly even worse.
Any guidance for me?

Best steel for flexible filet knife?

Grandpa wants a filet knife for Christmas and it’s gotta be thin with a nice flex because he catches lots of bluegills and crappies in his local lake.

I’ve never done anything thinner than a chef’s knife and never tried for this kind of elasticity so I’d love recommendations on a steel that will be relatively easy to heat treat to a flexible state.

Will any spring steel work well? Should I aim for a lower hardness than I would on a camp knife. Should I temper differently than normal? Any advice or helpful links are appreciated, thanks!

EDIT - UPDATE

Thanks for all of the quick replies! Looks like my best and easiest answer is 15n20, which is great because I have plenty on hand and know how to heat treat it. Will post the finished product.

Stock removal from leaf spring advice (uk)

This is my first post here after lurking for a few years. The Q&A thread seemed pretty dead so thought I would risk a post instead.

The leaf spring suspension in my van snapped and needed replacing. I remembered hearing that leaf spring steel was good for making knives. I was hoping I might be able to make some kitchen utility/ multi-purpose knives as gifts (with a fair bit of practice and terrible blades).

I've made one knife with a blacksmith as an experience day and really enjoyed it. That process involved forging a billet to shape. I'm not really in a position to set up a forge and anvil but I thought I could use those old leaf springs to make a knife through stock removal.

I guess what I'm asking is, what would I need? I've got an angle grinder, drill, and can get a decent set of files. Would a blowtorch be enough to harden a knife with?

I used to watch copious bladesmithing videos but when it comes to actually doing it, I'm drawing a little blank and would appreciate some input.

thanks in advance.

New to blacksmithing and bladesmithing. Today is my dad's birthday and in one year I want to be able to forge a nice Chef's Knife for his birthday.

He has some specifications he'd like and I want to surprise him with type of knife. My mom bought him a Dalstrong Shogun Series for $160 but he keeps hurt his hand on their old knives. We don't know if the Dalstrong is going to make a difference but I'd like to help him. He's sort of a chef so he puts his other hand on the back of the knife and uses it to leverage it. However it causes blisters with the old knives and he'd like that sort of curve curve at the bottom of the blade next to where the index finger goes when handling it.

Please Bladesmith Experts help me to learn the craft!!
