I'm looking for the Black OLFA blades. Aparently they are extremely sharp and not avaible to the general public but it would be very nice to use for tinting windows for perfect cuts.
Anybody?

 

Homedepot and Rona always have them in stock. look for the yeloow olfa case with the black sticker and white lettering on it. those are the ones.

 

Thanks for the help. I haven't seen them in crap tire here but maybe I'm not looking in the right place. Maybe I have to try a different store.

 

if you really want good blades for tinting windows you should try the olfa stainless steel blades. they are smaller than the normal blades, but they are awesome. plus they won't scratch glass. the guy at acklands/grainger told me they use fish scales to hone those black blades, thats how they get them so sharp.
