MK morse bimetal blades are to me the gold standard by which all other porta band saw blades should be measured. Recently, my blade supplier in North Chicago (a multi-generational industrial supplier) decided to stop selling MK blades because their tool supplier, Milwaukee Tool, complained and complained. I've been a long time fan of MORSE blades - so when I grumbled and tried some Milwaukee blades - I was furious! 2-3 cuts on a 1/2 square stainless steel rod and the Milwaukee blades were "done". Through. Nothing good. So I ran back to the supplier - returned the crappy Milwaukee blades - and hopped online to order my trusty MORSE bi-metal band saws. Work!
