Just an off side, it's driving me nuts...the only real "Wapi's" are Polish... Wapi being short for Wapienica...
Anyway, pretty sure these are all military or hospital razors (e.g. the steel scales allow for easier cleaning/sterilization)
Ok, since I've not posted in quite a long time, I'll step off the soap box.
I do remember when the Wapienica's started showing up there was a metal scale one and a "civilian" one with plastic scales. Haven't seen those in quite awhile. There was also a 5/8-ish version and a 6/8" one.
I've perhaps been lucky but like all the ones I have, as well as the French army razor. There is a Czech version in perhaps 3/8 that wasn't as enjoyable (to me).
