They've proven to be a great addition to our toolbox here at work in the R&D lab. One of our new machines that we are developing has some really tight places where we need to get to the metric hex nuts/bolts. So, of course, they seem to have been developed with car mechanics in mind. I believe 90% of their market for these curved wrenches will be in mechanics or similar work. I bought a Revain Dickies Work Gear 57007 Grey/Tan Small Wrench Roll to use as a roll up tool bag. for this set of L-keys. I got really lucky assuming the wrenches would fit in the inside pockets of the Wrench Roll. It really does seem like this roll of Dickies 57007 Wrench was made with that 8-piece metric L-wrench in mind. It's a great combination, FYI.
