Hand filling my first Karambit

I'm not sure what's going on. I'll check back later after I get some work done...

Joshua, I will definitely try this, as Richard suggested, gotta find 60grit sandpaper.

I see the pics now, looking good so far.
Good sandpaper is a must. I ordered about 10 sheets of each grit of Rhynowet red paper (between 60 and 2000).
It's much better than stuff in local hardware or automotive stores.

Thanks man, ill check out Rhynowet!
 
Got through the hard parts with sand paper, thanks for that! Now finished beveling but im worried whether i filed the blade too thin before the heat treatment. Also, it occurred to me that i have nothing to sharpen the knife with after its done...
 
How thin? You can probably take it to around 0.03" at the edge before HT. You can always do some hand sanding after HT it's just a bit slower going.

That's about 0.04 inches, right where you want it.

Awesome, would you tell me if my plan makes sense to you? Or if im heading towards total disaster? :p By the way I sanded the entire blade from 80-240grit so its quite smooth.

heat it to non magnetic, leave in for another 2-3 minutes max then quickly quench in 75 degree F water counting 3 seconds and taking it out then again in the water for another 3 seconds.

take it out and temper it in 400f oven for 30minutes.

Are these the steps i need to take?
 
You can search for HT procedures, 1095 has been discussed a lot. There is a sticky thread near the top of threads list that is a BF search tool.
I send mine out for HT, so I'm the wrong guy to give advice on that. I know the thickness is reasonable, because that's what the HT places specify.

I think the edge thickness is fine, you could even go a bit thinner if you wanted to. I am a bit concerned about the V-notches in the spine of the blade. I suspect if anything bad happens during the quench, it will be at the notches.

I know what you mean, I wanted to give it a bit of a post-apocalyptic look and I realized halfway through filing that this might cause a problem during HT. i Thought that maybe the thick 3mm spine would aid to a more solid foundation however, I'm sure it doesnt work like that :/

At this point, you just have to go ahead and quench it and hope for the best! I'm keeping my fingers crossed that you won't hear the dreaded ting. For the next one, it will be safer to grind the post-apocalyptic features in after HT, one more reason to get that angle grinder.

I think my heart will crack if the blade cracks, a lot of sweat and some more sweat went in to it hehe. I've decided to go with rapeseed oil (canola) as my quench liquid. I wanted to also ask just so that I'm prepared well for this, should i be expecting flames or a liquid explosion or something abrupt (other than a potential TING that is)? Thanks again!
 
If you submerse the entire blade, there will be no flame. There is nothing wrong with using a pot from the kitchen. My pressure cookers are pretty big and would require a lot of oil to fill up. If partially filled, getting the blade in would probably put my hand above the oil because the pots are pretty tall. Just do a dry run with water and the tongs you will be using to check if you can get the blade in safely in case you do get a flare up and to see how much oil you will need.

I do not know if 1095 will properly harden when quenched in vegetable oil, I thought it needs fast oil or water. Preheating the oil might help.
