I have not used each knife yet. I tested the 4” paring knife on a lemon that I had used to squeeze juice from - 4 days ago, so it was very soft from being in the fridge. My old knife wouldn’t city through without me piercing the peel, but THIS KNIFE?! It cut through like butter!!! I barely touched my finger to the sharpened edge and could feel that the first layer of skin was sliced a bit (thanks to the lemon juice). These knives are sharp and I’ll be a loyal customer for gifts and upgrades in the future. Love the products. I’ve purchased two sets as gifts in the past, now I’m treating myself.
