    Hi everyone,

    I've been having trouble getting some fine sandpaper marks off the blade after I changed grit. Here's the problem: I grind my blade up to 320g on the belt grinder then I go to hand sanding. I usually start with 320g lenghtwise then I go diagonally with 400g until all the 320 marks are gone. I keep sanding and sanding and I always see tiny little scratches leftover from the 320g. They just won't come off. The 320 I use is from a 50pk I got from Jantz a while back. The 400g paper I use is Klingspor wet or dry, I wet sand. The 320g says it's "silicon carbide" and the 400g is aluminum oxide, is there a major difference between the two?

    Today, for sh*t's and giggles, I got me some real nice 3M sandpaper and lo and behold in about 10 minutes the scratches were history. You get what you pay for I guess.

    I'm curious as to what sandpaper you use and why, and also where are good places to get some. I had stocked up on some of that Klingspor paper but I'm thinking that maybe I should get some better stuff. I don't want to be sanding any more than I have to.

    Thanks

    Rhynowet Red You can get it at supergrit . VSM is not bad but not great when it get to wet.

    I love rhynowet red! Just wish it was available north of the border. Last time I ordered I had 2- 50ct pkgs in my shopping cart and the shipping was more than the paper. :-(

    I use Norton Black Ice. It is a body shop paper. Mostly I use it cause I sell it and I get it pretty cheap. I haven't used anything else but this does a great job.

    i dry sand using Gator 280 or 320 and then move onto 400 and 600 wet/dry from 3M. I just recently started going to 800 and 1000 for a couple knives. I didn't think my knives were good enough to sand that well. I'm getting better though.

    ( gotta finish that light box. I want to show you guys some pics. excited to hear feedback...)

    Thanks everyone, I got some 3M and some Maximum stuff from Canadian Tire at 320g I'm going to give a try. It's when I go from 320 to 400 that i can't seem to get the darn scratches off. Once I get to the higher grits I seem to be doing fine.

    For the 280 to 400 I do fresh the old before going on to 400 fresh or do a cross hatch before going to lengthwise sanding
