It is stamped "MADE IN USA", Pat. No. 6,889,579.

Seems to only be usable on about 5/8" or larger. True or false and why?

I think there are two different models. One for smaller bolts and one for larger ones.

Hi, everyone who know what is the differnt loggerhead bg8-01r-01 vs loggerhead tools bg8-01b-01 thanks.

1R is slightly smaller width for the handle spread (4" vs 4.8") and lighter by 1.6oz. It also does not come the the "certified frustration-free". I own the 1B and it is exactly 13mm to 20mm for the working end. The 1R only lists the max as 3/4", so it could be slightly smaller opening (.75 vs .787) on the 1B. Their website currently only sells the 1B. However, at 20mm (fully open) the handles are so wide apart that you need some basketball player hands to really get the bionic effect. Works best under 11/16 or 17.5mm. And if you ever come across the 10" (BG10-01R-01 or 01B), buy it, for it is no longer manufactured. I think they had issues with the lifetime warranty when people were trying to use it on large nuts and bolts.

Would this be a good tool for a mechanic ? Is useful with most bolts ?

I found it limited to use on bolts. The size of the bolt head is restricted to small or med. I found many of my bolts did not fit.

Flexible and useful

Very handy having a single spanner to reach for instead of digging around in a toolbox. Especially when you work with both metric and imperial bolts.

Not a five star item.

I should have looked at the sizes it would fit as this eight inch wrench will not fit plumbing 15mm nuts but even with that it's a nice idea and works well on other nuts and pipes. It's not bad for the price but not a 5 star item.

but it's not as good of a grip as I was expecting

It does the job, but it's not as good of a grip as I was expecting. I should have just bought and ordinary adjustable wrench.

多分、米国製だと思いますが使い勝手も良く最高のアイティムだと思います。ただ値段が少し高いと思いますが・・・耐久性があれば我慢の範囲内かな。

Pros • Incredibly handy tool - does the job of several others • Great grip on bolt/nut • American made original - not the Chinese made rip off Sears is selling • http://abcnews.go.com/US/MadeInAmerica/wrench-inventor-claims-sears-stole-idea-china/story?id=17720122 Cons • Smaller manufacturer may take additional time to build & shop * nothing that should prevent you from ordering one Highly recommended!

Enfin un outil avec de la torque !... Pratique, facile à manipuler, fort. Essentiel au coffre à outils. Finally a tool with torque !... Practical, easy to handle, strong. A must for your toolbox.

No agarra a la primera. Necesitas un espacio del largo de la herramienta para poder girar. Muy cara para lo poco y lo mal que lo hace. Tardo en llegar mucho tiempo. Muy bonita pero no sirve para un uso normal, ya no digo profesional. Totalmente desaconsejable.
