These "T" handles are supposedly going to get caps made for handle storage. Just a thought on what they might look like:
One with removable mounts, externally butted seat tube, and straight gauge DT. The top one has a seat clamp, internally butted ST, double butted main tubes and is LHD.
I made the handles from the same sticks that these fork legs were made with: .058"/1.25" dia 4130. They're definitely a little heavier but can be swung at full force. The heads were modified by the CTY guys. The (multi-purpose) shape seems to make digging packed dirt easier than a spade shovel and still works well as a transfer shovel.
