Actually, the polearms are made of a hardened wood shaft turned at the local lumber mill then add what looks like a Wooden bow without a string made of steamed ash peg mounted then bound with sinew to the shaft. They are used in groups of two or three with a batsman and the reason for the use of wood is that it is an abundant local resource.

The tactic is easy and adjustable, one traps the walker at the waist, the other traps a leg usually against a building or they trip the walker then pin it to the ground, once pinned the Bat is swung it's length giving it extra force as well as keeping the attacker at a safe distance to deliver the ending blow

These weapons can be scaled up to be used from horseback 

Cavalry Sabers are as yet uncommon but I can see at least 100 being found in the course of 14 years and worn by only those that prove themselves as leaders and capable of using the weapon. The Primary weapons of Troopers are Lance, Bow, Lariat, and issued firearms under a special provision. Scouts are more likely to Carry Firearms but their main weapons are the Bow or Tomahawk which they are experts in the use of. 

The reason there is no production of sabers is because Lasthope is currently working on making revolvers and lever action rifles, they have a Black powder mill that is picking up production enough that at least the town can allow weapons practice with new black powder stuff 

Oh forgot to add that they are also working on nitrocellulose-based but the production pace and quality need work
