Fish/Eel Spike (Ikejime) handle and safety cover

Spike used for humanely killing fish. (IkeJime or Ike Jime)
This design of spike is very common (e.g. on amazon for 10 bucks) but suffers from a lack of safety cover and grip.

The handle uses x5 10mm self-tapping M2 screws for assembly.

Most printers should be able to bridge the handle cavities fine and print without supports, but you can have a bit underneath if needed.

No supports should be needed for the safety cover.

The safety cover is printed so that it flexes a bit when sliding on to tightly grip the spike.

This is the spike I purchased, but there are MANY vendors selling this identical product:

I would also advise putting a slightly sharper tip on the spike, a few passes on a diamond plate or fine sand paper would be enough.
