You should check out the outdoor edge razor edge. They have a replaceable blade like the havalon, but a lot safer blade change design, and the replaceable blade can be sharpened if you want. Outdoor edge also has a folder with the replaceable blade and the gut blade. The gut blade is reaaly nice because it has a rounded edge so there is no way to puncture the gut. I have a buddy that has both the havalon and a outdoor edge and now he only uses the outdoor edge.
