So far I’ve sharpened about 5 knives on the KMFS kit. The kit is precisely made, and I must say that the selling price seems very favourable to me after I’ve had a thorough look at the kit. I also bought the recommended diamonds for the kit. The results astonished me. Simply a perfectly sharp knife, sharpened exactly to the set angle. After the first sharpened knife, I learnt to control the kit with my left hand too. The resulting blade is polished and perfectly sharp. So to sum up, this is a super product for a super price (I simply bought something for knife maintenance instead of another knife).
