So I purchased a used Swamp Rat Rodent Ruck. The condition was a lot more used then expected. There is a good amount of groves ( the best decriptio. I can think of) on the blade sides. The blade itself really needs to be reprofiled there are lots of different angles how ever the edge has held up great other then being very dull!! This is my first blade of this type and wanted to see what angle I should be going for. I planned on reshaping with a work sharp with belt attachment. Any advise will be greatly appreciated!!
