The Pike Pole, a nautical themed weapon, presents just that. it gives a brief history of this sort of weapon and how they have been used along with ideas for a how a character could have learned to use one.
Several variations on the pike pole, both mundane and magical, are included each with its own illustration. As are rules for trip and disarm attacks using the weapon. All well and good except it is a tool turned into a weapon that is just better on all levels than weapons made as weapons.
As listed, it does not have the heavy or two-handed properties yet has reach and does a 1d10 damage for 5 lbs of weight and 1 gold (or 5 gold if you want the improved one that gives you a small bonuses with the maneuvers). It is a spear with a hook, it should do spear damage (1d8) and have both the heavy and two-handed properties to bring it in line with other pole arms (and the trip and disarm should be added to other weapons as well, if you are giving out those maneuvers).
A good idea and excellent presentation of the weapon, but it just too good mechanically. However, that is easily fixed.
