Neck Knife Build Along (WIP)
« on: July 11, 2017, 01:14:44 PM »
Working on a trade with one of our members.  My end of the deal was to build a neck knife.  I started Sunday and thought today that I'd do build along, or work in progress thread.  I didn't take pictures of a few steps, but will explain.  I will take pictures of the rest of the steps.

First the steel.  Thought I'd use a rusty sawmill blade.  The blade with the larger teeth started out as a 54" blade.  The smaller one was about 30".



Next was to cut out a couple of pieces - one from each.  I used a 4" angle grinder to cut two pieces that were about 4" X 7".  Next I annealed them in my oven over night.

Next was to cut some strips with my portaband band saw and knock off some of the big chunks of rust.



Next was to profile the blade.  The secret to profiling is to remove the parts of steel that don't look like a knife.  Sometimes that works, sometimes the grinder and steel have a mind of their own.  This is what I came up with for a profile.



I'll get back to it after supper tonight.

Since I don't like to fire up the heat treat oven unless it is full (process is just so time consuming), I profiled a few more and drilled them.  Next up is the heat treat process.

Heated the blades.



Quenched in Canola oil.





They are going through a temper cycle now.  Will repeat the temper cycle in the morning.

The heat treat is done.



Time to work on one at a time.

Grinding.



More grinding.



Grinding with a 50 grit belt is done.



Grinding with a 400 grit belt is done.



The scales are from 2500 year old bog oak.





White liners seem appropriate.





Ten pound of BB's to help set them in place.

Tonight was attaching the scales.  Tomorrow I'll shape them and work on a sheath.

I like those bamboo-skewer pins that you've been using......a little different than the run-of-the-mill nickel or brass that you see most of the time.  Mosaic pins are a little too much for my tastes. :shrug:

Wet forming is done.  The sheath needs to dry overnight.  Should finish things up tomorrow.

Beautiful end result Dave, thanks for the tutorial.

I know nothing about knife making, but I was just wondering, after you tempered the steel and you profiled the blade, I noticed that you didn't profile the edge before heat treating. Is that because you were using a pre-heat treated sawmill steel? I always thought a blade was ground within a few thousands of the edge thickness, heat treated, and then finished the edge?

I annealed this before I started.  After the initial profile and drilling for the pins, I heat treated the blades.  I like to heat treat the blades before I start grinding because I have found that there is less chance of warping during the heat treat process.  The trick is then that you have to be super careful while grinding to not change the temper.  That took a bit of practice, but so far, so good.

This bog oak really intrigues me as a knife handle material, both its appearance and durability/longevity really appeal to me.....maybe because I'm in the early stages of fossilization myself. :-\     I'd heard of it before, but didn't know the particulars or advantages of using it for knife handles.  It almost sounds like nature's version of wood-micarta from the Wiki description.....

How was it to work with, Crash.....any impressions or tips you are willing to share?  :shrug:

This was very easy to work with.  I know who sent it to me, but not sure where he got it.  He can chime in if he wants to.  My experience with bog oak is pretty limited.  The first knife I made with it was recently.  I personally cut a few pieces off the log that it came from.  It was very dense.  Of course, there is quite a bit of cracking on the log, which I'm looking at filling with a contrasting color - it might make for an interesting effect.

This piece was quite a bit lighter than what I have used before.  Again, I don't know the history of where it came from.

I see that there are several Ukrainian vendors on eBay that sell bog-oak scales.  I have ordered stuff from China and it came faster than most things I order from the U.S.A......but I don't know how fast Russian mail is. :shrug:
