So i took my bk7 out camping, no problem. cut down three trees about 4 in thick each. easy. coating held up awesome. but i wanted to strip it, remove the thumb ramp and add the notches i shaved on the now straight spine (bk17 inspired). stripping went great, used klean strip and took maybe 45 min. i sanded at 180, 220, 300 something, 400, 600 and 1500. it looks great, but i have some serious grind marks still. question is, how can i remove them, i want it all to be smooth and also is there a way to maybe darken the blade a little. i like the shine but id prefer a flatter light grey. To be honest i miss the black coating a little haha, but i know its just the new factor. thanks guys. enjoy!

Grind marks

I also noticed really small "pits" i guess youd call them throught the handle. and i almost lost the laser etched bk&t and bk7 on both sides... sad

a rough render of my plan

Looks great, I have some klean strip, but wondering about using it in the cold temps here.

Start back over at the lowest sandpaper level, and alternate directions between levels. ALSO, don't move on till the current level has removed all of the grind marks.


Once that is done if you heat up some vinegar and dip the knife into that it will darken it, however long you leave it in there it will get darker and darker.
 
I de-ramped my BK9 and I'm thinking that I might do the same to my BK7 as well. I did it by hand last time. This time I think I'm going to go buy a belt sander and save my digits the file pain. Keep us posted on how it goes! I like the feel of my BK9 much better without the ramp. Never finished it off with jimping though.
 
Looks good. Love my stripped 7. I have the stamped version, but would love an etched version. You could have done the PCB Etchant solution before stripping it to engrave the laser etchings deeper into the metal to keep them around a bit more. No worries though. Looks great. I like the ramp, myself... but I'd like to try one without it... I'm considering getting a second BK9 to play with. I'd probably take the ramp off of my current one if I did.

the pic with jimping is a render i made on photo shop. i wish i were that far along haha. the file i bought isnt up to it so i have to get a heavier duty one.

that laser etchant wouldnt work at this stage? its too bad ive lost most of it, and since more sanding is required, im sure im gonna lose it all.

what kind of file did you use, anything specific, or special?

Well, the PCB Etchant solution is a mild acid that disolves the metal. When you put it on the laser etched coating, it will eat away at the bare metal below it... but not affect the coating... so it will basically imprint what it laser etched into the metal. If you put it on now... it's just going to eat away at the metal, since there is no stencil to etch.

With my BK9, I use a soldering iron to melt/scratch away at the coating to stencil out my user name one side and my Beckerhead # on the other. then once I stripped the entire coating, it was deep enough to remain.

Dylans, nice work so far! Taking the ramp off without a belt sander is gonna be tough. Adding the jimping will be almost as tough without a Dremmel or something similar. That 1095cv is wicked tough so be patient and tenacious. Good Luck.

Uncle Malice, thanks for the tip. I tried using etchant and stencils after stripping but was not happy with the result. I'll try your method next time.

what kind of vinegar? just plain vinegar? and heat to boiling, then put it in, or heat to a boil and boil with knife in?

Apple cider vinager. It just sounds better...That reminds me about a joke about kermit the frog and miss piggy and something having to do with pickled pork...not suitable for this thread..
 
white vinegar will be a light grey patina, apple cider vinegar will be a much darker, almost black patina, depending on how long you let it sit for.
