Recommendation? 3M Microfinishing Film

[Dragons Breath Knives]

Good day to all!! Can anyone recommend the most common progression for using the film for finishing out Blades! Any Pros and Cons? Thank you in advance!

I tried it and didn't really like it. Too stiff.

I use the 3M clothlike polishing papers. The order is already in the set - 400,600,1200,4000,6000,8000 - green, gray, blue, pink, mint, white.

Just one of many sources:

Various options
Micron 80-40-20-9

Finishing them out how and where? They have many uses...

I like them for folder handle shaping and finishing Mostly using the shoeshine method.

Or spine and choil work

I want to add that when I use it, it is for sanding inside curves, like choils and finger grooves. Habeer's grit progression is good.

Normally, grit progressions go by roughly half/double the grit size.

You can get the 3m Polishing sheets for about a $1.25 from TruGrit and K&G knife supply.

Do the polishing sheets leave J-hooks like regular sand paper?

Sand paper do not leave J-hooks. People sanding do

The very high grits polish and the scratches are so fine you can not seem them, the lower 400 and 600 you can see if you J hook.

Yeah I know. I'm always looking for a quicker way for the perfect handsanded satin finish if you know what I mean.

I find going up higher on the belt sander with cork belts makes hand sanding much quicker
