I need some help understanding the different knife edges available, their purposes and the best way / system to keep a nice sharp edge on our tool. I just recently purchased a DPX HEST Original knife and put it through some paces this past weekend. First, the HEST was not as sharp as I would have liked it righout the box. Second I always have used a ceramic stone to clean up the edges on other knives I have and it has worked fine. What I have noticed is that the edge on the HEST is a very sharp angle compared to my Spyderco pro grip, Victorinox outdoorsman and Laguiole pocket knife, that these edges are nicely tapered and with a few passes on the ceramic stone we can preform surgery.
