Lapping film is always 5 stars.
Always.
Always.
Yup.
Black smudgies and such only add character to film. If we come up with some fancy, foreign names for the discolorations they will be seen as desirable.
The film doesn't slide around on the marble? What grit would be good for touching up a razor that's been honed recently?

Brooksie you really need a bigger and slicker surface. Heavy glass 12" x 3" or bigger. Dont limit your real estate and make sure it is slick enough for a good vaccuum between plate and film. I use a polished marble edge tile. If you want to try film, dont ignore its potential advantages and dont cripple it or you will only be disappointed.

This has probably been answered somewhere... Im about to buy some lapping film and was wondering if 3m and diamond lapping film was the same. and if not which one should i buy? which is better?
nanolaptech doesn't have all the info I'd like up on their site, and no online ordering. Did you call or email and did they answer questions quickly? I want to know sheet sizes and how small an order I can put in. I've only got one straight, but two kids that occasionally manage to get into the area I'd be storing the film in; so I don't want to drop a lot of money on film that isn't likely to last long enough for me to use it. I used to live in the same town they're located in, which makes me want to but from them.
If money is no object, go with diamond film I guess, any brand. But if you are like most of us you will find that while the diamond film does last longer and cut a bit faster, there is not enough difference to make it more cost effective than AlOx or SiOx or other abrasives. Also diamond film is usually sold in smaller pieces. AlOx is usually sold in 9x13 or 8-1/2x11 sheets. Diamond is often in 6x6 sheets and so you can only get a 6" stroke. Part of the advantage of film is a longer, wider honing surface than most stones. Don't give up this advantage by trying to hone on a 6" long surface. So actually unless you can find full sheets of diamond, you really want AlOx. 3M is just a brand, one of many.
A more important decision, actually, is whether to go with PSA back or plain back film. Most of us greatly prefer plain back.
Last order I placed was with www.nanolaptech.com. They have a great variety and excellent prices even in small quantities. www.thorlabs.com is another popular vendor.
.1 is HARSH for the bathroom. YMMV. LOL
This thread is incredible.
I am about to order my set of films. What particle sizes would you recommend for a starter set? Sorry if it has been asked before, this thread is over 60 pages long...
Btw, my desk is compromised of a huge half inch thick glass plate, do you think i can just use that as a flat surface?
