Dishwasher Safe Kitchen Knife???

[kdnolin]

I appreciate all your different suggestions and advice. Summer has been so busy that i have only been in my shop to do some sharpening since May. last night I went out to see what I had for steel, no CPM 154 big enough, but I have an AEBL hidden tang blank (210 mm Gyuto) hardened and almost ready for a handle. I'm going to try the JB Weld and keep the handle simple. Frequent sharpening is not a big deal for me, I use my 2x72 and leather strop. Now i need to find shop time!

You can't make a guideline or a rule that somebody won't break, but you can make a knife that a dishwasher cant break.

i want to add you might be able to get away with iron wood least for a bit but it turns black in the dishwasher i know cause my father had his 2 full tang knives put in the washer by otherr fam that was helping clean up post thanksgiving dinner the stablized maple popped (i use 1/8 pins non peened) up a bit the ironwood didnt move and the 2 ton epoxy held tight. now here is why i dont peen the pins. i can carefuly punch th epins out pop the scales off clean the tang and the back of the scales and repin and epoxy them right back on. this keeps any spa treatments or repair costs low

We recently tested composite panels at work to see at what temperature they delaminate. I don't recall the exact numbers, but West Systems 105 was somewhere around 120°F, System 3 slightly higher. If you have a sous vide machine, do a test piece with whatever epoxy you plan on using and set it to 160°F or so and see if it survives for a couple of hours. Or just use JB Weld as butcher_block suggested.

Forget JB Weld , there is other better option .Try Polyurethane Sealants For Automotive (Vehicles). Most are black color which is good thing . They can handle temperature , it is flexible , water and detergents have no effect , it will hold scales on the knife even without pins.On one of my grinders i used it to glue ceramic plate behind belt ,it is pain to take it off ....I make several handles with this .One was for my brother and that knife is in dishwasher every day .Wood was walnut ........but not ordinary walnut .It is high heat treated wood for furniture .I don't remember anyone ever mentioning that type of wood here . Thermally modified wood was more dimensionally stable , increased heat resistance and weather resistance as well. When properly maintained, it will not chip , rot or warp over the years , absorbs less liquid...........well make search for heat treated wood if you want more data ..

I ran an experiment at home for a whole year, two 14c28n stainless knives, paper micarta handles, one with pins and the other with three corby bolts. They were used and cleaned with the dishwasher daily, no special care taken.
The one with pins unglued, its still usable but you can see the gap in the photos. The other with Corby bolts remain perfect.

BUT

OTOH the one with pins micarta handle is a solid piece of micarta, the one with Corbys if you look at the back of the knife with a loupe you can see the delaminated micarta, but its only anecdotal because the handle is still solid and there is no sign of integrity degradation. The steel we all know have no problem at all.

PS: why the hole in the blade? to stop a crack that I saw when the knife was almost ready. Not ready to be sold, perfectly good for my home use.

I would buy some commercial NSF approved knives and let her use them as she likes.

I think you're asking for more pain to do otherwise as your hand made works gets damaged by the dishwasher.
