should there actually be "indestructible" weapons?

Should something even exist in GURPS terms if it's maximum HP is 0?

I could see assigning fractional HP for low-mass objects like house flies and mosquitos but not 0.

Even a million DR can be penetrated by ignores DR unless the DR is cosmic or hardened.

I have no problem with this long as we don't confuse it w/ undestroyable.

B376's "break" when compared to B401's "Breaking a Weapon" which cites B483's "Damage to Objects" which mentions "Homogenous objects, such as
swords, bend or break, but might remain partially usable" on the same tier as merely a "severe malfunction" on the level of falling unconscious for living beings.

B484's roll at -1xHP on the other hand is more like destruction: "a sword
might shatter instead of merely bending or snapping" which is the "destroy" equivalent to 'death' for the living.

I'm thinking B376 is more like B483's result than B484's result.

One could argue that there is some negligible form of mass (as energy has) in the blade per E=MC2.

Does this mean batteries get slightly lighter when you use up their stored energy, I wonder? I figure on some low-perception per https://physics.stackexchange.com/qu...ged-discharged

So the amount of mass the force sword's battery loses when drained divided by the time that mass keeps the sword up could probably give you some sort of "mass existing in the sword in a given second" maybe?

This doesn't work well w/ continuous math but more in a discrete kind, like "mass expected which creates a sword for a 1-second period, then requires more mass from battery to create another 1-second period".
