The worksharp guided field sharpener is awesome, I use mine as my main sharpening stone these days, the diamond plates are good quality and last a long time, cuts steel fast, and the built in guides help me maintain an angle.
I’m a good freehand sharpener and can shave hair with my knives without using any guide, but I use the guides on my worksharp field sharpener, they are easy and help minimize the human element.
Really easy to get every knife I own shaving sharp quickly.
Plus it’s cheap enough to have several, one in the truck, one in the pack, one in the kitchen, and one at work, etc.
I also have the bigger worksharp bench stone tool thing that swivels to match the belly of curved blades, it’s also amazing and stays on my kitchen counter, plus they sell an expansion kit for it that adds an extra coarse diamond plate, and extra fine diamond plate, and a leather stropping plate.
I haven’t used my Lansky, dmt stones, sharpmaker, various benchstones, fallkniven DC 3, or any other sharpening equipment except for my belt grinder (for reprofiling) since getting and using my worksharp stones.
I also have the worksharp ken onion belt grinder and while it’s good, I much prefer my harbor freight 3x30 belt grinder.
