Key Blanks

Alright, so I got a Key-Bar a couple months ago, idk if y'all have heard of them. But the wy they work is there are 2 screws and you put your keys on them and it works like a folding knife. My question is, does anyone know where I can get key blanks for standard house keys and master lock keys that have the single round hole instead of the big hole. I need one like these so they will work good with the screw system.

As apposed to these

But I can't find them with the right slide pattern. Only in awkward slide patterns that won't work with regular locks

 

Something like this?



Never had any trouble with it, and I don't think any of the keys have the design you're looking for. I really like mine.
