I use several different types of knives in my kitchen and need them to be super-sharp. I use several small paring knives, several sizes of Chef's knives, a Nakiri, Carving knife, Butcher knife, Boning/Filet knife, Vegetable knife, etc. I used to use a pull-through and honing rod, but they weren't getting my knives sharp enough. I reviewed several different types of sharpening tools - the sharpening system was too complicated and required assembly to sharpen a single knife - too much work. The pull throughs didn't get my knifes sharp enough and didn't provide for different grit stones. The Warthog Vj-Sharp A4 was exactly what I needed; simple to use, a variety of stone grits and it gets my knives unbelievably sharp. Watch a few videos and use an older knife for your first try. The 325 grit is good to fix up an older knife blade that has been abused, but a bit coarse for my knives because I do keep them so sharp. I purchased the 600 and 1000 grit stones, using the 600 grit most of the time, finishing up with 1000 and a leather strop. It takes me about an hour to sharpen 25 or so knives and they are so sharp (razor sharp) I have to be careful because they slice deep into my cutting boards. Most of my knives were between 15 and 17 degrees, so I use the 15 degree setting for all of my knives. For me, this was the perfect solution - so easy to use, I can sharpen up a single knife in about 5 minutes and put the sharpener back in the box and in the pantry. Definitely Recommend

Ordered this because my son-in-law had one and swears by it. This is a guy that always brought his wet stone to my house to sharpen my knives on holidays. I found it very easy to use and keeps my knives consistently sharp with minor touchup.

I'm not a hunter, I'm a cook. I'm not trying to sharpen a penknife or a machette. All I want is a sharpener that's stupid easy to use, Won't ruin my kitchen knives and keeps them razor sharp. I want a precise grind angle and I want it to work quickly. The Grizzly is that sharpener. It doesn't produce a burr because it sharpens both sides of the knife at the same time therefor you're not trying to lap it off. You can strop the knife if you want but for normal kitchen duties it's not necessary. I had my vintage Sabatier 'professionally' sharpened which meant it was sharpened on a band grinder and a load of metal was ground off. Never again. I will sharpen my own knives from no on using this South African sharpener. Highly recommended.

I have been using one of these for about 7 years now and am fully satisfied with it. I don't understand the people trying to flip the blade around, I've never had to even think about doing that as mine still works as intended. I think that some people are trying to resharpen really dull knives with this and that's what the problem is or that you have it set wrong for the angle that is on your knife. I take all of my knives and sharpened them on a TSPROF KO3 at a 20 degree angle on each side, I then use tis to keep them razor sharp, it works perfect like this. I couldn't be happier. The quality of this unit is great when used like this.
