I still have 3 Dexter wooden handle carbon steel knives left from working at my dad's store in the 60's. Plus, I got a new 5' curved stiff boner with extra texture grip handle from Koch Supplies that I like very much, makes it easier boning our pork butts.
Also, my dad had a produce knife I inherited, that he kept on the produce table for trimming lettuce, celery, beets, cutting up watermelon, and on and on. It was invaluable to him! I wrote Koch to see if they still had them but they said they'd never seen one; if he got it from anybody it would have been them.
Upon closer examination, i realized it was something he made himself on the meatsaw, cutting notches into a SS dime-a-dozen knife:
You can see the uneven gaps between the 'teeth', plus variations in depth too. If you ever need a fantastic produce knife, and can cut metal on a bandsaw or use a disc grinder on edge, this makes a great one! It has cut and trimmed thousands and thousands bunches of celery, trimmed off the dark button on heads of lettuce, cut up tons of potatoes, trimmed broccoli, carrots, rutabagas, onions and on and on and on!
