Knives north of the border

[Tubby’s Canteen]

Good afternoon gentleman, in viewing some of the beautiful pieces made by Von gruff I thought he may be interested in seeing some of the knives made here in Canada.

Not wanting to hijack his post I decided to start my own.

For some reason they did not attach the first time.

If those are your first knives then they will function as intended so now there is a little design, fit and finish to work on but any start is a good one.

Those are around the fifteen to twenty mark , the first ten or so were complete failures. I had a hard job finding the proper temperature to temper the steel.
I use steel from a water powered bandsaw mill blade. Similar to a single buck only wider and thicker.
Mystery steel and a coal forge made it a learning curve to achive hardness without being brittle.

Watch out for those "boarders", sometimes they stay too long!

Most bandsaw blades are 15N20 so treat is as that when tempering at 375-400 for 2 hrs. Are you doing the full heat treat (anneal to work then harden before the tempering)

I am , the bandsaw blade is hard enough I'm forced to anneal it. The secret I found was multiple thermo cycles before quenching.
This blade came out of an abandoned water powered mill and it appears to of been blacksmith made in its own right. Interestingly it was designed to cut both up and down. On a fly wheel and pitman arm style jig.

If I may impose what do you quench in? I've been useing heated used 80-90 gear oil up til now.

Blade making is new to me , I learned to smith on horse shoes out and ox shoes.

For carbon steels I quench in a 2 ft deep/8 inch dia (old fire extinguisher) with canola oil heated to 130*I grind the 1095 shallow hardening steel closer to finish (it needs a very fast quench to get the best from it) than the deep hardening 10 xx (84 and 75) 15n20 HT's similar to the 10xx(75 & 84) as does o1 and d2 tool steels.
For the 12c27 stainless I plate quench
