EHS FTCS (F-Type)
Aluminum tube made out of very hard quality aliminum often used in aircraft industries. This alloy is more expenive but keeps the bent better than other alloys.
The tube has a cnc machined slot in the bottom in the shape of the bent.
This very precise machining job makes it possible to create a nice and smooth prebent blade.
In the QCS and the FTCS the side walls are prebend cnc machined to create a very precise wall thickness of the lips This very difficult process gives the original blades the special feel.
