This is the metric set of offset ring spanners and the prices for these do fluctuate and still remain at a reasonable or sensible price, not like it's cousins the Imperial, AF, Whitworth sets. My next buy will be the imperial/AF/Whitworth set if one can find them at the right price as they have gone to silly money.

The imperial variety will eventually become either extinct and/or obsolete like the DoDo, as metric is the most dominant of the species as newer cars come off the production line all now with metric bolts. The manufacturers deciding to favour the combination spanners, those with a ring on one end and an open end on the other.

Personally I prefer this offset ring spanner design, (or 'Swan Neck' as it is sometimes called imperial or metric). Most mechanics familiar with this design will understand where I am coming from when I say they are good for manipulation in akward places and the can interlock allowing for extention, a positive contact with the nut with it's ring depth.They also allow for a good grip generally by their design, why reinvent the wheel?

Since I am talking on a personal note: After owning a sets of metric and imperial offset ring spanners they decided to take a walk-a-bout, straight out of my garage one day and disappear, 'Puff!' into thin air, knowing where they have gone is based upon keeping the peace, however leaves a diappointing taste in ones mouth, as the spanners have not returned, perhaps one day......
Until then, I have purchased a replacement set of METRIC offset ring spanners, (above) based on a low budget buy.
(If only my original set remained in the garage... All donations welcomed!).
