I had an RD-7 that would fall out of the sheath when held upside down, no matter how tightly the velcro strap was fastened.
The scales didn't align w/ the steel.
It hurt to chop with it.
I recontoured the scales, which helped quite a bit as far as feel, but I knew I'd never grab it first, so I sold it.
I much prefer Swamprat or Busse, but granted, those cost more. In the same price range, I'd look at the RAT-7
