Unusual saw teeth. Normally, they alternate one tooth at a time, but these are in groups of two. The sharpness of the blade is about 50%, assuming a freshly sharpened blade is 100%. Old saws often have handles that are stuck and won't come off, but this one is not a problem. I will, of course, send both the handle and the blade separately. Please refrain from price negotiations, except for bulk purchases. Also, please consult beforehand for bulk purchases.
