I have been using these knives for at least 20 years. They are the only knives I use since I own 6 of the different styles. If you want a knife that stays sharp year after year then this is the one for you.
I have not used it yet to slice tomatoes. Waiting till tomatoes are vine ripe. I do not buy tomatoes at any grocery store as their all tasteless no matter how much you pay for them.
