GrimReapers. I have shot hogs, shoulder, gristle plates, blown thru. WT with backbone hits from above, broke the vertebrae into 4 pieces, not 1 broken blade!!! Double shoulder shot on WT, no broken blades. Have only had 2 blades break so far and those were on impact of something in the dirt. I know this for there were 3 blade cuts on exit holes. Had 1 skip off the sternum and cut 4 ribs on exit and remained perfect. I re-sharpen all of them afterwards and reuse them. I have several that are going on their 4th or 5th time out. Take a look at them and you see. GrimReaper Razor Cut.
