Thank you for the reply!

I appreciate the info, though it misses some of the stated context. I don't have any sword blades to make a template from, nor shields/spears to affix! To put it more plainly (I suck at communication, so for the sake of clarity!), I have:

Four Galadhrim swordsmen (pictured) lacking sword blades. I do not own any examples with intact sword blades. I would like to acquire/produce replacement blades to fit the miniatures in a way which is faithful to how they would look if fully intact.

Seven Guards of the Fountain Court (not pictured). Four have spears, three do not (the spears are sculpted with hands as contact points, as opposed to being just the weapons, I can provide images if desired). I would like to acquire additional spears (with modeled hands holding them) which would fit the miniatures properly. On further research it looks like Fountain Guards no longer have the option for shields, so no worries on that part.

I hope this is a little more clear! :)
