Thread: Types of sandpaper abrasives

Yet another newb question... What type of sandpaper abrasive is the best for using on razors? Where are you guys getting it from?

I just bought a bunch of papers from Harbor Freight, and I've been pretty happy with them. They are all Emery, 60 through 220 grit. The problem is the finest they have is 220 grit. I bought some 400 grit from Home Desperate, but it's *very* expensive, and doesn't last long at all. So I guess really what I need are some pointers to some good 400, 600, 800, and 1k grit papers. I was thinking of getting some from here... Bullet Wet-or-Dry Sandpaper 9″ x 11″: Wet-or-Dry Sandpaper 9"x11"_p Bullet Industries but it doesn't say what type of abrasive is used in the paper.

BTW, the 40 micron and 15 micron 3M films used for sharpening are *fantastic* for sanding... they cut *fast*, but they are too expensive, and the gap from their 15 micron to the next finest is too large.

Help?

It is always good to check the Wiki first: Hand sanding a blade - Straight Razor Place Wiki. The progression of grits is towards to bottom.

Yup, I've read every page in the wiki, and that page numerous times. My questions weren't answered, hence my post.

I'm not asking about progression of grits, I'm asking about the types of *abrasives*, and where to get them.

Up til now, I've only been sanding up to 400 grit, then using a vibrating polisher to finish, but it's taking too many days this way, so I'm planning on sanding to 600 or maybe 800 grit now.

Well, it is getting late over here. Apologies for the mis-understanding.

Get sandpaper from the auto supply shop, it is usually silicon carbide wet dry sandpaper, you can get 220, 400, 600, 800, 1000, 1200 and 2000 grit.
The price varies depending on the brand... 3M is rated as the best but is expensive, there are cheaper brands that will get the job done, most auto supply or body shop will carry other brands.

Hope this helps

Oh, good idea! There's so much great information here in the forums, but it's so scattered around... putting it all in the Wiki is going to help a ton.

Last summer I fixed some rust on my car and I still got the sandpaper it's 1000 and 1200 grit paper that I got from a store that sells autoparts and stuff. Now I don't know how it is where you live but check out you local store that sells stuff for your car.

At Harbor Freight I picked up a multi pack of sandpaper with grits from 500 - 1500. However when sanding some yellowheart it left some grey specks in the wood that would not come out. Of course since that was the only sand paper I had it didnt really help to keep sanding with it. I believe the sandpaper was for metal so that may have been the cause, course it also could have been cheap chinese junk from HF not sure.
