It might be a Metrinch “clone”, or it might be a modified version of the Peugeot Freres “Surpans” wrenches, which were also made in the USA by New Britain as the “Nut Master” style wrench.Thanks for the answers!
I have another one that is marked 19 mm & 3/4", a rather natural correspondance. I think I have more but don't know where exactly, when I find them I will check if they also have double markings.
The shape of the IUS wrench quite matches the Metrinch profile (i tried to overlap them, not sure if it really tells something).
It can turn a 10 mm nut, but it is very sloppy, there is something like 15 or 20° of play between the two directions. It makes sense if they are designed for both metric and imperial (and English?) hex sizes, the extreme flank design must be more forgiving.
The open-end seems very dangerous for fasteners, if not fully engaged, it looks like it can round corners very badly...
Thanks for the “heads up” on those Mr Lemons - that’s a stupidly cheap price.


Hey @Vicks why did you go with the non-comfort grip on the crimping pliers? As I buy more knipex pliers, I find I like the comfort grips in the 180mm and under sizes. The 200mm and larger sizes are very bulky.

Fluke owns Pomona. The Pomona 5519A test leads are virtually identical to the Fluke TL71 test leads (just some slightly different stamping around the manufacturer name).Pomona leads to replace the Fluke leads.
I have Pomona leads at work. They are very nice and flexible. I know Fluke make silicone leads as well, but I'm not sure if they are worth the premium.
Exaggerated (but not by much) comparison between PVC leads and silicone leads, showing how PVC leads stay all bunched up after they have been wrapped up in storage. These Fluke are particularly bad as they are quite thick. It's not so much of an issue with thinner leads.
I did not know that Pomona leads are 'New World.' They are however common in the UK and available from the well known electrical suppliers here.

I noticed that the protective caps were interchangeable from the Pomona and 101 leads (TL75?), but didn't think anything of it. Thanks for the info.Fluke owns Pomona.

I’ve never used any myself, but I see a bit of Unior around. It seems to be sold by places that sell things like screws and fixings, and the customers want a tool that works. Doesn’t have to be a big name, but needs to be half decent.
That's the exact packaging i bought mine in. The softfinish is good by not being excessively soft (and spongy) and all over the handle. I think the hard black tip blades lasted better than the full chrome ones, No ?Haven't seen those available in the USA. Interesting that the tips are black instead of blasted and chromed. Looks like the blade from the discontinued 3K series with a handle from the Softfinish series.
I found a photo of the box with a web search.

Show quality nickel and chrome plating is ~.003" thick. On something like a screwdriver it's half that at best; this is certainly not going to change the fit.

Very nice. Do you know if 130s are discontinued? I cannot find them on the Unior website or catalogue. Cannot really find anything about them anywhere.
