Any cut-on-contact fixed blade should do the trick. I would look at the magnus line (buzzcut or stinger),g5 Striker or Montec (standard not magnum), and possibly even the Slick Trick Standard (these are 4 blade but very sharp). Cut on contact head and a 1" diameter head you should have no problems with. I would steer away from mechanicals until yourboy is pulling more weight and creating more KE. Good Luck.
