A couple from this week

[jindydiver]

I am fortunate to know a good many people, and one of them is a pro knife maker who is having a sabbatical this next year. He had to move to Sydney and needed to store some gear so I offered him some of the space in my shed to use. He surprised me by giving me a whole bunch of stuff to keep, and also by telling me I am free to use his gear for the year instead of just tripping over it. :D
I got the bug this week to test out the belts he gave me (trizac) and the blast cabinet, so I dug out some of my L6 and got to work.

I am amazed at the efficiency of the belts and the blast cabinet is definitely going to get heaps more work yet.

Here is what I came up with…

I love how I was able to get the hamon to stand out by using the blaster. :D

That's awesome Jindy 8)

They both look like very handy little knives. Did you already have the profile and then put the edge on, or did you start from scratch?

When you make your knives, do you get the desired shape laser cut first, or would that be considered cheating?

Dave.

Very nice work Jindy.

I really like the brightness of the handle material against the steel. :D

I don't want to sound dumb (whoops too late) :lol: is the hamon the material you used on the handle?

Cheers Noel

There is no such thing as cheating, as long as you know where it come from and if you are going to sell them you tell others where it came from.

This is where the steel comes from

That’s ok mate, here is a snipped bit of your PM so others can know the answer too.
The hamon is the line you see on the blade where the steel has a different temper. The edge is much harder than the rest of the blade and so the blaster can't abrade it as much. You see the same thing on the classic samurai swords.

I chose a bright colour for the handles because this sort of knife is more often kept out of the way and camo would just see it lost when you put it down somewhere.

Are the whole saw blade made out of the same steel?

[jindydiver]

Yep.
The bigger blades are very good quality steel because of the need for the blade to stay together when subjected to the forces applied to it during use.
You can’t guarantee the steel until you test it though. I cut off a few smaller pieces and heat treat them and then test them by bending them and beating them with a hammer. The most common steel used in saw blades of this type is L6 (or something with almost the same makeup) and from my tests I see no reason to doubt that these ones are L6 too.

Mick,

Are all your bevel edges done with a linisher or is there a better tool for the job? I use linishers at work and I am way to inconsistant at keeping the edge the same.

[jindydiver]

I have 3 diff' linishers here and that is all you need to put the bevels on. Oh, and heaps of practice :D

[Wareagle]

So what do you use to cut it out of the saw with, oxy?

[jindydiver]

I use a 4 inch angle grinder with thin (1mm) blades designed for stainless steel.
When I get my act together sometime over the next 2 weeks I will post a tutorial of how I do the knives
