I am sold and in Love with these blades, My experience before getting these was if the blade lasted for more than a nail or two I got some kind of use from it. The First blade out of the package cut through 68 brad nails and 18 finish nails without skipping a beat. The edge on this blade is impressive to say the least. I tried to cut some oak trim with the same blade and it not made for woad, but hey I am happy to change the blade if it cuts through nails like it does.Even though the company never responded back to the email I sent them, I will be buying more as I need them. The other companies better take heed to how Imperial makes their blades or they will all be cutting just wood.
