For now, I'll just use it straight-from-the-tube. A 10ml tube (about the size that lip balm comes in) is $6. I can probably do 100 knives with that.
I'm just sayin'...with these Fine Tip Transfer Pipettes, you could get the drop smaller...I have used them to transfer vey tiny droplets of blood...sometimes with older diabetics, that is all the blood you can get from their finger...just a fleck, nearly.
Still, unless OT had a place to aquire some...I don't know where we'd get 'em. They are pretty expensive and not worth the cost. If they were, say, free...might be worth you trying...just to get the appropriate-sized drop.
Just for the record... my HH knife (I have the serrated version) is still tight in all respects after many many hours of snap-click snap-clink practice.
