Modifying Melee Weapon: How to make a melee weapon with a telescoping handle?

[Anthony]

For a mundane mechanism, the big problem is that anything telescoping by that much is going to be super flimsy when telescoped. If you're throwing in magic, the obvious option is the Extend Object spell.

You can also add more damage with Accessability only when large or only when swung.

GURPS PU 4: Enhancements p.21 explains that what you said "Thrusting Blade Enhancement, +15%" is used to convert cutting damage into impaling damage. Light Horse-Cutter and Dao already have both attack modes, so I don't think there's any need to use this enhancement.
I still don't quite understand the suggestion to add Damage using the "Accessability" Limitation.
Among the enhancements provided by GURPS, is there an enhancement that adds damage? As far as I know, Damage is determined when specifying the level of Advantage before applying the Enhancement. This is because the basic value of the required CP is calculated based on the level of the advantage. So it's hard to imagine how you apply the extra Damage you're talking about.
If it means to spend additional CP according to the sentence "Calculate the “effective point cost” for each mode, as if it were the appropriate type of Innate Attack." in the Melee Weapons section of GURPS PU 4: Enhancements p.10 , I haven't found an explanation yet that this can directly increase Damage.
If you have any ideas on how to add damage, I'd appreciate it if you could explain.

Given its weight, however, you would need high ST to wield it one-handed - 8 lbs would normally call for ST 13, but a weapon like this is going to be rather tip-heavy, so ST 14 to use one-handed.

If you're wanting to use the light horse-cutter with Broadsword when the handle is extended, I'd allow that, but you'd need high enough ST to be able to wield the polearm one-handed. Well, I'd actually reduce it compared to what the normal rules are, but that's because the normal rules are a bit ridiculous here - I'd probably let you use it at Reach 2 one-handed with ST 16.

I would use the guidelines in Low Tech Companion 2: Weapons and Warriors for giving a polearm a shorter handle, here. So, -1 to swing damage, and -1 to Reach, for Reach 1. As the weapon is just as heavy as normal, MinST doesn't get adjusted.

For a typical one-handed sword with an extending handle, I'd treat it with the handle extended more like a Naginata than a Horse-cutter. A Horse-cutter with the handle reduced is going to be a rather oversized sword for one-handed use.

When the handle is extended, this weapon is essentially a Light Horse-Cutter. I have no plans yet to wield this Polearm with one hand like the famous generals in Northeast Asian historical novels like "The Three Kingdoms". My character will use this weapon with the Polearm skill after the handle is extended.
I think the idea of ​​applying the effect of Short Handle from GURPS LT 2 p.13 when you reach 1 using the Trick Weapons mod is great. The problem is, this mod is designed to work on the Lich 3+'s very long Polearm. So I think I'll have to discuss this with the gamemaster.
The reason I dare to refer to the Light Horse-Cutter as a Dao with a Long Handle is that the Horse Cutter used in Northeast Asia (especially China and Korea) is a weapon called a Podao, and this is precisely a weapon that adds a Long Handle to Dao. because of.

As you can see from the image, the Naginata has a thinner and sharper blade compared to the Chinese Podao. Traditionally, medieval Japanese warriors preferred light and agile weapons rather than large and heavy ones, so the Polearm they used was also developed in a relatively light form. , I think this is enough to explain the relatively light weight of this weapon)
Of course, I totally agree with your comments that the Horse-Cutter with a short handle would be a rather large knife for one-handed use. Let's talk with the Gamemaster about your proposed equipment performance tuning procedure.
Thanks for the detailed reply!

I am clearly aware of the reduced durability when giving the handle a telescoping feature. Your point is valid, but as I said before starting this discussion, the setting for this piece of equipment is a world of magic. Of course, you could simply enchant the handle to stretch, but I wanted to consider the mechanical method first. For my taste, that method is more "cool". Of course, it would be easier to use the Extend Object Spell, but I would like to avoid using magic as a universal tool to overwrite the part where I can add a more plausible explanation.
I agree that your suggestion is reasonable. Thanks for the proper answer.

Have it twist into a locking mechanism.
