I got these Park T-handle allen wrenches a few months ago. I love the sliding handle with detents, the "spinner" sleeve and the unique stripped bolt extractor end. Included is a 2mm size for the bleed port on Shimano hydraulic levers. The sliding handle lets me use the 4 or 5mm wrenches on water bottle cages. The 8 and 10mm sizes are bigger than other sets I've owned, and work great for removing pedals. A bit pricey but definitely better than any other allen wrenches I've owned.
