I love my xikar. 6-7 years old. Oiled it a few times and had to retighten some loose screws once. Mine is the all metal version, but it's not made for opening beer bottles. The blades may be extremely hard but the body will scratch and dent with abuse. They say it will cut up to 54. I cut alot of Perdomo Squareds in half with mine. They drew alot better after that.
