I have a few pocket knives around the place, but always have this one on my keyring when I'm out: Spyderco Honeybee Stainless. Sharp as you like and deals with most of the 'dangers' I run into in the city :)
I looked at UKtools where I got my 1/4" spinner handle. There are several 3/8" listed https://www.uktools.com/socket-drivers.html but none with the yellow translucent handle like the 1/4" I got.
Received today:
Koken 1/4" spinner handle and a couple small Koken 2400M 1/4" sockets that I was missing. The handle is a little smaller than I anticipated, but is very well made nevertheless.
I noticed Supadriv screwdrivers in a Vessel catalog.
I’ve never run into Supadriv screws. Where are they used, and is there an advantage over Pozidriv?
Can you use Supadriv drivers with Pozidriv screws?
It's also worth looking at lesser known German brands, where you might find some decent deals. Among others: Athlet and Arndt for screwdrivers, Orbis and Saltus for pliers. In Europe these can be found on Amazon and/or eBay.
