Some pictures, and experiences, if it helps.
Below is a 12 inch Crescent, made in the U.S.A. I don’t really know how old this tool is, but I’m thinking at least 70 years, possibly more, and I’m the third generation of my family to use it.
I know Crescent didn’t invent this pattern (that was Bahco) but this is the best I have encountered. It’s stronger than any other of the same size, the parts fit better, and despite all the use is still free of slop! This is the standard against which you should judge all others.
Here is an original, Swedish made, Bahco that was left to me by a friend and I cleaned up. It’s a very good tool, strength and fit are excellent, but the Crescent is better.
Here’s a newer ”Bahco”. Made in Spain in the Irimo factory. I actually bought this tool for a plumbing job before acquiring the Swedish one. It’s not a bad tool. It can be seen that the pattern is styled like the original tool, but is different in a number of respects.
The overall quality is not as good as the Swedish tool. Note how the amount of metal has been reduced. The fit and finish are not as good either.
Finally, here is an Irega tool, Stahlwille branded in this case. (10 inch too, the others shown are 12’s). I bought this as I wanted a chromed tool for my road box.
I think the quality is a fraction better than the Bahco branded Irimo, but it’s obvious that the Irimo products vary in both design and quality, according to the brand name they are going to bear.
I’m not sure if this is the case with Irega. All the Stahlwille branded Irega’s I’ve seen seem to be very good, but dukefx said above that Irega’s get loose too easily. I think I’d agree with that, certainly from the older examples I’ve seen.
Finally, the Crescent, Swedish Bahco, and Spanish Bahco can be compared. The strength of the Crescent is notable. I don’t have a 12 inch Irega to compare.
