As most know, more than one brand of blade will fit some mult-tools. I thought this might be a good thread to start, so we would have a common reference as to which fits which. Yesterday, I went to Northern Tool and checked to see if their GENSIS (Power Smith) blades will fit my HF tool. They do. With a coupon, I was able to purchase two bi-metal blades for around $11.00. I also bought their wide (2-5/8") flush cut blade for $9.99. I need this to do some siding removal.
