I recently bought a Cold Steel Gladius Machete, a Cutlass Machete, and an Accusharp Sharpener. Accusharps are well reviewed on the Sword Buyers Guide site. The Accusharp did am amazing job on the machetes. I posted an Amazon review that said Cold Steel should include an Accusharp with every machete Accusharp also makes a ceramic V rod sharpener called a Sharp N Easy. This works great for a final honing. I never really thought pull through sharpeners worked, but, they work great on machetes.
