Iki jimi spikes are difficult to find in the UK. Rob Allen make a nice one with a good sheath (important) and a tri-cut point but its pricey:
I've made some iki jimi spikes using thick round awl blades, placing them hot in a thermo-plastic chainsaw-file handle and using sections of an old telescopic car aerial/antenna as sheaths.
However, these days I prefer to use the impressive tri-cut spike on my Rob Allen fish stringer, if I am close to my float.
Otherwise the much smaller, less sharp spike on my Omersub nylon waist stringer or my cheap flat spearo dagger).
However, I just came across a veterinary tool called a "veterinary trocar", which could perhaps be used as an iki jimi spike, to dispatch fish humanely?
e.g. the 5mm or 7mm version of this:

I believe they are designed for piercing animals (e.g. for bloat), stainless steel, and available in various sizes. They often come with a stainless steel canula, which could perhaps be fashioned into a protective dive sheath?
