Update,
For about a week have been waiting for a revert from the machinist i had given the blanks to do the bevels. He called back today and told he cant do it right.
Have decided to now either get the appropriate wheels for my bench grinder or get a dremel tool to get the bevels done myself.
Any suggestions/advice guys?

You'd do well to go in for your decision...
1. You have control on your time
2. No dependency or be at the mercy of external sources
3. Decide on your own need of the bevel angle
4. Sharpen your DIY skills
:cheers:
Briha

Use a relatively smooth wheel, and try to get a bench grinder with a speed attachment. Start with the slowest speed. If you can rig up (or have) a jig to hold the knife at a constant angle, so much the better. Even if it is a simple block of wood to which you attach the knife so that when you hold the wood vertically, the knife is touching the grinder at the desired angle.

Dremel is not so good for bevelling - it is too slow and runs through the accessories at a tremendous rate. Best kept for smoothening jobs, etc.
Cheers!

Nice knife! Blank reminds me of a Becker BK2 http://www.amazon.com/Ka-Bar-Becker-BK2 ... B001N1DPDE.

Do you plan to heat-treat also? Since you mention getting steels, did you know that the rusted steel sometimes found on construction sites (they use it for reinforcing concrete makes a very good material for knives?). As do leaf-springs from old suspensions. Basically, its high-carbon, that's why it rusts. :)

You may try making a Micarta handle for your knives instead of the plain acrylic ones. You can use fiberglass resin or epoxy for forming the micarta. check this

Heres a closer look at the transparent handles...

Hello Kshitij,

I love to collect utility knives, but I have never seen a knife with a transparent handle like you have shared.
Thanks for sharing as my next pick for knife would be of the same kind.
Keep knives in your pocket and pray that you will never need it

Hi PB,
Does it really look like the becker? I never noticed that ;)
I do not heat treat any of the blades i make since the sheets I use come pretreated. What i meant by getting steels is sourcing particular kinds of specialized steel in the sheet form so that only just have to cut the blade profile out of them. I am no expert at knife making and my level of competence is restricted to hand sharpening a razor edge to my knives :P , Use machines to do all the profiling work on the blades as well as scales.
I am aware of leaf spring steel or rail road spikes being used to make really good knives but since they've spent a longgg time under stress and are in a particular shape, one would have to anneal them at least a couple times over, then flatten them, normalize, and see if they still have a memory. To me that is just too much work :stupid:

Hi Anand,
Yes micarta scales are on my mind since a really long time. Its just that the acrylic ones are easily available and doable so the lazy bum in me doesn't have enough drive to get going on them. have now started using 6mm thick teflon sheets for the scales as they are really durable and grippy. not to mention they are very easy to profile to fit your hand...

Hi harshit,
I made the acrylic ones on an impulse and they have lasted me just fine. But i am not sure there are many mainstream guys who do that, maybe for a good reason I am yet to find out :P
