even if an axe dosen't cut trough your chain, it will easily brake your bones, especcially hands/ribs. (a battle axe, or a great/longaxe, not a hatchet)
i know a lot of people who chain, mostly they use 4 in 1, sometimes 6 in 1, and for show-off 8 in 2 (just double the 4 in 1).
they use steel links coated in zinc (Zn) to make it shiny (

) and stainless, but no matter how you coat your rings, sweat will rust them, because of high concentration of salts in it.
so, you have to wipe sweat asap and oil your chain from time to time.
knights used to have their pages put a chain in a barrel partially filled with sand, and roll the barrel downhill, then roll the barrells up the hill, then down the hill (sizif, anyone?

)
it definitiveley removed the rust.
/and for the plate armours, well, they polished them with their own piss. and it acctually kept them clean/
and if you use steel rings there is no way you can open/close rings with your fingers, you need a pliars in each hand.
anycow, back on topic - Altay, keep us posted on the preformance of that new sling/flail of yours
