that's a tough one, 6 months ago, but the second left I think looks like a Felo
I have sets of Felo,, PBSwiss, Stahlwille, Walter, and odd Hazets.
I like the Felo 500 best, the triple scalloped profile fits the fingers well, and the thumb sits in the curve to the ferrule land really well; The handles are easy enough to clean grease off, although In practice I have now kept them for woodwork exclusively. That is a sort of indication too of benefit of the grip ; 'natural' selection in action!
Wiha always feel like the main ridge/bump is too pronounced (for me).
The PB Swiss handle texture is very good, good grip results from the longitudinal grooves in the handle; good for oil and grease free jobs.
Stahlwille handles are ok, and buggers to get grease off.
Walters I keep in the office for electrical and house set.
The lower one, the stainless and blade rotates separately to the handle; used for titanium lock screws in spinal plates. Also demonstrates a 3 scallop profile, and given the application, this tells one something about design criteria. Note the Felo has a similar profiled handle; 3 scallops and flared lead in to the ferrule land.
. I was probably too focussed on an aluminium-coloured body. The only thing different is that it has no speed knob (or it's duct-taped off, hard to tell, because it has 2 speeds on the tag), and mine has 620W. But they're definitely very closely related, maybe mine is an earlier version because it has less power.
