Progressor Wood Cut Jig Saw Blade

The Bosch 4-1/2" Progressor Wood Cut Jig Saw Blades, were bought after buying a different brand that just didn't last. These blades seem to last roughly three times as long as the blades I had purchased earlier. It has been my experience that blades of this kinda always start thier lives by performing fairly well but then losing thier cutting ablilty quickly.The Bosch blades are aloso a little stiffer,indicating a harder metal.I did manage to break one but that was not due to the quality of the blade. The stiffer sharper cutting action seems to leave a much smoother cut than the standard blades I was using before. The accuracy of the blade is very impressive this to I believe is due to the stiffer composition of the blades.The Bosch blades ae another shining example of "you get what you pay for". I would suggest checking these out before spending money on a lesser quality blade. The time and effort saved is well worth the little extra cost involved. I would reccomend this blade over most any other I have used or abused. I won't be trying the cheap stuff as far as blades go the next time.
