I suppose that the issue of blades falls into the category of "What You Don't Know About, You Can't Miss".
I started my interest in wood working five years ago and purchase a couple of combination full kerf Forrest blades, they were recommended to me by Mark Mueller of Incra Tools.
I have tried some thin kerf Freud Bllades along the way. I have used all of them for both cross cuts and ripping and, I have to say that in my inexperience I see no difference in the way any of the blades cut for me. The cross cuts and the rips are satisfactory for a person like me that doesn't know the difference or what results I should expect.
The expression "ignorance is bliss" is probably applicable here.
I recently had one of the Forrest blades re-sharpened, after betting it back from Forrest it cut just like it did before I sent it in to be re-worked, it needed three teeth replaced, but it was still cutting just fine in my opinion which is not a very sophistigated opinion.
As anybody knows that reads my threads and posts on this forum, they know that I am not afraid to show my lack of understanding about things that are just common sense to most people, but man do I get a great education from members that gracefully attempt to set me straight. So, I'm waiting to hear what is going to be said about my observation of the cutting results that I have described.
This may cost me some money once I am more savvy about what I should be looking for in a blade. To me as long as the cut is straight and does not burn as long the feed rate is constant and reasonable, I'm happy as a clam. I will say that I do experience burning when I get overly careful and feed slower than I should, but that is my fault I suppose, but maybe not, heck, I don't know.
