Check this site out if you need a high temperature cement.

That's probably a really pricy hi-tech goo.

Don't know about price, but it's been around a long time. I used it
at work in the '70's. Hmmm. 4 oz. for $13 for one type. I remember
it being very hard, but was tough, didn't crack even under heat
cycling in a furnace. I'd have to look at the literature to decide if
any of their products would work for the knives. Seems overqualified
for the heat part, don't know about the moisture and adhesion needs.

I think I'd try a highly flexible, waterproof adhesive instead.
Either Plumber's Goop or E6000, which are very nearly identical.

Dry the handle, use a toothpick to work some adhesive into the recess,
then push the cleaned stainless part in. Dry overnight, then pare off
the squeezeout. That should fix them for your lifetime, at least.

If they don't have notches (handle and knife shank), make a few for
better retention.

Be careful with any solvent-borne, evaporating-type adhesive in such an enclosed application. They shrink a lot and not necessarily where you want them to.

That's a job for a thermoset, and it's hard to beat a high-quality, 100%-solids industrial epoxy.
