The Chapman Manufacturing Master Set is awesome:
(remember using a set with fondness when I was in the Air Force)
and after mentioning it on /r/BicycleGear, a company rep at: https://www.reddit.com/r/BicycleGear/comments/6ajthj/ratcheting_hex_key_set_imperial_and_metric_from_a/dho60hm/ offered up a discount code:
You can use the code “BicycleGear” for 15% off the Master Set. I usually only give codes around the holidays, so maybe that’ll persuade you to buy one Here’s the link https://chapmanmfg.com/products/master-kit-5575
Unfortunately I’m not in a position to buy it (blew my discretionary funds on 10 45 and 10 more 60 degree endmills from drillman1 on eBay) — but if anyone else can make use of this, highly recommended.
