Cate,
While I don't own any of these Buck Culinary knives at this time I have sharpened many over the years.
First, Your method of a hand wash is far easier on the edges. The wonderful chemicals in DW detergent will frost the edges and you lose sharpness within a few washings.
Besides, If it was for washing Knives it would be called a Knife washer.
On to the knives in Question.
My only desenting vote on these Buck knives is that if you look at the chef knife in the last picture you will see that it is a Hollow grind, While they will cut very Keenly as new, there will be a time after many sharpenings that the cuts will wedge,
After the hollow you have one thickness with a slight distal. I prefer, Make, and sell Full Flat Grinds to make sure the owner/s can get as much life out of the knives as possible with the thinnest least restrictive cross section as possible.
While this set may cut fine for a few decades? There will come a time that they will be sharpened pry bars.
Your mileage WILL vary!
