I have been using Olson double/reverse tooth PGT 9RG blade for cutting 25mm oak. I do not have tight curves so they have been great. I have tried other blades but these were the best and had the longest life. Unfortunately my supplier woodworkscraftsupplies stop trading this Spring. Does anyone know where I can get them in the UK. I have called Yandles and they do not stock them. In fact they implied they are phasing Olson blades out. I am not surprised because those that they stock you can get better equivalent Pegas blades. The only Olson double/reverse blades I have found are multi-packs of 6 each of 5-7-9RG. The 5RG are of no use to me. Any help gratefully received.
