I just received my order today (very fast shipping). I ordered 1 gross (144) of blades from Mikesworkshop
Half are 2/0r and the other half 5r.
I had never tried them before but after reading a few posts here, and reading up on Mike's site, I ordered them.
These are the best blades I have tried. I was breaking Olsen 2/0r blades one right after another, I did 5 ornaments out of 1/4 red oak with just one blade and it is still sharp. I am also about 1/2 way done with a 6" tall Celtic vine cross using one of the 5r blades, cutting 3/4" red Maple. It's cutting like butter. No more Olsen or Dremel blades for me, I will from now on order these excellent blades from Mike.
