Ken Onion Edition Knife & Tool Sharpener Mk2 - Professional Knife Sharpening System for Kitchen, Hunting & Outdoor Tools | Perfect for Chefs, Butchers & Camping Enthusiasts

I purchased this and immediately upon receiving it began to sharpen all of my knives. I am very particular about my knives so I never let them get dull or chipped. I have been using several different types of sharpeners over the years however I love this one. I have now put 38 different types of knives (total of 60 knives) through this sharpener now. My hunting knives were slightly dull before starting and the rest were of fairly good sharpness. Below are my impressions.PROS:Very consistent edge angle that is VERY easy to duplicate every time. The angle adjuster is so simple to use, it never moved on its own and is very easy to see and feel.The machine motor stays consistent RPM and does not slow or minutely vary in speed when pulling a blade through.The belts are super easy to change and having the belt centering adjuster is a great feature that is much appreciated.The knife angle guide is super easy to remove when doing gut-hook edges and then to re-install afterwards.CONS:The little plastic roller wheel on each pull-through guide are of a soft plastic that the knives will cut into even with light pressure.The speed adjuster is not in a good spot, every time I pull and release the trigger it slightly creeps up in RPM as the wheel ever-so-slightly rotates when I place my finger back on and pull the trigger. It should be a 4 or 5 indexed speed setting wheel on the motor housing somewhere, no need for it to be on the trigger and it would greatly help if indexed.I personally found the angle of the handle to be very flat and after an hour of using this tool my wrist started to feel the strain due to the angle. I do realize that many will not spend over an hour straight using this tool and I typically won't either however I wanted to put this tool through its paces.I read that many people had issues with it scratching their knives, this I can only assume is do to improper use. I was initially a bit worried about it scratching my knives due to so many comments about it, so I started with a few hunting knives. I carefully followed the simple included use instructions and I never so much as put the faintest of scratches on any of my knives. I have a really expensive set of Wustof kitchen knives that I sharpened every one with this tool and just like all other knives I put through, they came out the same as when first purchased from the manufacturer. I used the 6000 grit belt to finish off the edges on all of my knives as I like an incredibly sharp edge on every type of knife I own and the edge looks like polished chrome this does such a good job. Even sharpening the gut hook on several of my hunting knives was a quick and easy task that now has them razor sharp again. I also read about many people rounding the tips off their knives, again, if you read and carefully follow the instructions you will always end up with razor sharp pointed tips. Even on my fish filet knives the tips are still like a needle, you just need to stop the belt before pulling the blade completely off the belt. I gladly give this a 5 star rating and not only would I buy this again I have already been recommending this to friends and family. Worth the price considering what just a good set of sharpening stones will cost and those are much more labor intensive to use correctly.
