Or even cut, though that might produce its own weird interactions.

How in the world would a trust with a weapon gonna produce cutting?

Re: [Basic] Questions regarding Heavy Plate Armor
 

Sufficiently broad, sharp but un-pointy edge at the end would do that. Imagine something shaped like an axe-head and positioned like a spear-head. Pretty sure there are weapons written up that do that, actually.

Re: [Basic] Questions regarding Heavy Plate Armor
 

Several thrust cutting weapons appear in GURPS Martial Arts. Most such entries represent the effects of pulling with a sharpened hook (e.g., bill, hook sword, sickle, and sodegarami) or dragging a point to deliver a tearing cut (shuriken used to claw and spear used for a Tip Slash); here, thrust damage is shorthand for insufficient chopping power to merit swing damage. A few others reflect "swung" cutting weapons that offer insufficient leverage to merit swing damage (like the combat fan and straight razor). Still, several exotic weapons (deer antlers, knife wheel, lajatang, monk's spade, slashing wheel, etc.) do true thrust cutting damage by pushing a sharpened crescent into the target. It isn't unknown.

By having a broad edge on the tip? For an extreme example, look at a shovel.
