Re: OOC Stuff
Interesting question:
That leads itself to many different concealment opportunities.
I am throwing a few loose ideas here for now...
So, probably relatively cheap, since these are made of wood and are not designed to be actual weapons, although I am sure you can poke an eye out with one irregardless.
If you want these to be weapons for you, I would suggest putting a Weapon Skill slot into them, and then have a set of custom pins made for you. Probably going to cost less than a real dagger, since you are not creating a pommel or keeping an edge. It will be just a pointy metal stick with light decorations on the other end. I can't see this doing more damage than a dagger, or dirk, to be more specific, and they do 1D4 as purposeful weapons.
I am going to throw down an idea that they will do 1D3-1 (minimum 1) damage if they are wooden non-weapons (actual hair pins) with a 50% chance of breaking on any solid hit that does damage. 1D3 damage if they are actually built as concealed weapons (made of metal, sharp tips). I would say that if you want plain and utilitarian weapon pins, they ought to cost 1 gp each. Easy to forge, nothing more than a point or two and some decorations. If they are crafted with finer details the cost will go up. The regular wooden non-weapon ones are most likely going to run for 1 sp a pair, since they are decorative and will fetch a handsome price from the ladies who desire them, and might even be cheaper if you are willing to forego the "pretty bits".
If they are silver, they will probably run around 10 gp for the weapon ones, and maybe around 3 gp for non-weapon ones. Again, they are small, not much metal to them.
I think that sounds reasonable.
Thoughts?
