So, I plan to make a 3D printed katana for a cosplay prop because local laws dictate that owning a real metal katana is a HUGE no-no. 3D printed ones for cosplay prop use is fine though provided it doesn't look too real (anime katanas are fine depending on how they look)

BUT, the slight OCD/perfectionist in me demands that I make my katana as accurate as possible to actual forged katanas, with all the individual parts and hamon and all.

So I need some help. Big time. Questions in the captions for the images.

Appreciate all the help I can get.

For the tsuba. 1) Does it have rounded edges on the sides? (Shown here is the WIP one, with the edges rounded off). 2) Should I make a, uh, IDK what to call it. A slightly lowered layer?

The Kashira. Do I make it a separate piece for fitting? Or it's all built into the tsuka's back end? I was referencing a Youtube 3D print where the kashira was a separate cap of sorts you covered the back end of the tsuka with (and glued).

The fuchi. Do I need any specific things to it?

I can't find any help on what I'm trying to do and been racking brains for days now for this.

Gist of the issue is that I want to reduce off all the material on this block to make it a slightly bent, ellipse shape block using the highlighted area (in blue).

I could just extrude normally, or hollow the block to have the hole where I need it to be, BUT the problem is this block has a curving bend (something like what you'd see on the sheath of a katana or curved blade).

If I extrude normally using the highlighted area, I get a straight pipe without the cover at the end. Which really doesn't look like a sword sheath at all.

If I extrude and hollow using the intended shape of the block, it ends up with sharp edges and I don't want that either; makes the sheath a... ergonomics nightmare.

How do I extrude/reduce such that I end up with the proper shape I want?
