very clever with the wax. Awesome vid.

Well thanks for the help and I'd love to see if spray paint works. Ill be trying this out on my becker soon as a test to see if it'll work with my logo and ill subscribe to you cause I loved the video! BTW I can't reply to your other comment cause I'm on my phone.

Would there be an easier way to put small sharp right angles on the knife so that you could put a logo on a knife? I'm getting the knife I designed made by someone and so far nobody can put my logo on it without charging me a lot. and as reference my logo looks like a sniper scope.

[SrJoben]

@guardians38 You could paint the whole blade and carefully scratch out the lines of your logo. This would be tricky but possible. I'd suggest a practice piece first. I'm not sure how small it would be practical to go. Most of the stuff I've tried so far the designs bleed a little.

[guardians38]

@SrJoben I was thinking that I could coat the whole blade in candle wax and then get a small headed screwdriver and maybe push it out of the way or maybe cut the logo out of something thick and place it where i was it, coat the blade and remove it. Do you think that either of these would give me the sharp lines the I'm looking for?

[SrJoben]

@guardians38 It depends on the wax. Some is too brittle and will just flake, also it might not stick to the surface. I'm experimenting with spray paint for this right now. It's easy to scratch lines in it with anything pointy. I'm not sure it will resist the acid I'm using though.

@SrJoben seems like you guys are missing a trick here....sticker paper. draw your design and cut it out with a razor blade, stick it onto your knife, paint entire blade, let it dry and then use the razor to peel off the sticker of your design, and you have a perfect crisp outline of your design.

[SrJoben]

@DutchTheGunner Yes that works.

@SrJoben in anodizing they use rubber cement to mask the parts they want to protect...

You might want to degrease the blade with some cheap isopropyl alcohol before paint masking it.

I'd also use the opportunity of the knife being apart to Flitz the area where the PB washers touch the blade to increase opening smoothness.

[SrJoben]

@sae1095hc The alcohol is a good idea. I actually did polish the pivot area a bit. I didn't show it though. It came toward the end of the roughly hour long process of removing the nail polish and polishing the rough surfaces left by the acid that I decided not to inflict on you guys. :)

Thx a lot joben.

[dfivdayz5]

thanks for makin this..i tried it on a tenacious from your other video and it turned out pretty cool

[GeoMikeCache]

Nice job! What kind of acid did you use for this?

[SrJoben]

@GeoMikeCache Oops forgot to show that. This is a LONG process, got hard to remember what i'd said toward the end. It's ferric chloride solution, you can buy it at Radio Shack in the USA labeled as PCB Etchant.

[GeoMikeCache]

@SrJoben Aahh ok. Thanks

[egol14]

you sure have alot of those knifes are they cheap?

[SrJoben]

@egol14 Yes they are fairly cheap, it also helps that I sell them for a living.

[TheJebus88]

is almost the same tecnic what i use for make circuit almost

[MyHollowpoint]

That's a very neat process and the results are awesome.
