Phillip I need to get some of those. The saw I got from Cathy had one on it and it was just too wide to really use on the inside cuts. I didn't see them last night at Woodcraft. I am possibly going to HF today I will look there and see what they have.
I thought that I picked some up at WC in Winston- I might be wrong - I really like mine - I have the 1/4 inch but I am going to pick some 1/2 up as well - www.mikesworkshop.com might have them - not sure - that is where I get my FD blades
