Buckingham Mfg have a history dating back to 1896. Climbing spurs were handcrafted in their blacksmith shop and formed the genesis of an entire product line serving linesmen and arborists. Today they are perhaps still most well known for climbing spikes and port a wraps, but make a range of other tools including harnesses and more. There equipment is generally "over-engineered" and suits the climber that likes the feeling of security that gives.
