We can’t do this for now because the engravings are part of the blade’s mold, but if this idea gets more votes, we’ll try to think of something to do.
here is the one we did : http://www.calimacil.com/weapons/spears/telescopic-spear.html. We also work on new design.
this is a very complex weapon to produce. We will see what is possible to doMikael commented
You already have the 152cm(jo) staff. Both the Naginata and the Kira staff is over 180cm so you already know how to make long weapons. All I want is a simple wooden staff around 180-190cm. If it could look like the Raijin that would be great, but a simple wooden one will do.
If it is sturdy enough (Not totally rigid. It should have some flexing) I could also probably make use of it in kung-fu martial arts practice.
