the description says that the spurs protrude "wrist or knuckles."
unfortunately our GM has convinced the rest of the group it should be taken literally so that cyberspurs cannot be located anywhere else...

any help in producing an argument to the contrary would be most appreciated

Well common sense would suggest that if you can fit a spur to come out of the wrist or knuckly, you can fit it to come out the other way through an elbow (possibly more useful than you might think if you've never done a martial art that makes use of elbows) or some other places. The counter would be that if it were an unusual place then cost would go up as it's less standard, and barring the possible damage you could do with a razor sharp elbow, knuckles and wrists seem the most natural place to mount them in terms of usefulness.

Where did you want the spur and why?

Ah, the joys...look under the Combat Active Skills section for the description of the Exotic Melee Weapons Skill.

Realistically, the major limitation for a spur is placing it parallel to a long bone and not stabbing yourself whenever you deploy the damned thing. Standard placement to come along the hand allows you to use normal Blade techniques; the more usual unusual placements are coming out the back of the arm by the elbow (elbow spur) or along the shin to come out near the knee (knee spur) and each requires their own specific Exotic Melee Weapon Skill.

Have it come out of the bottom of your foot.
Skill needed is break dancing

Djinni,

take a look at page 112, exotic melee weapons, as Ancient History suggested.

the description on exotic melee weapons finished with "cyber-implants weapons in unusual locations (ie. elbow spurs, foot blades)."

I have used the elbow placement as well as along the shin coming up at an angle in front of the knee. That particular Sammie was trained in Muy Tai. Made those knee kicks very deadly. The movement issue was avoided by only deploying the blade just before he actually delivered the kicks and retracted them immediately afterwards. We counted that as part of his training so it was done as a matter of reflex.

The tailor bills must have been hell though...

Well, if the sammy get's along well with the mage, the spell fix should take care of that problem in a jiffy.

Foot blades is what I thought when you brought up cyber spurs in unusual locations....now I can make my X-23 cyber spur sammie

So your a female clone of a runner named Logan who hand razors and some deltaware bone modifications.

Of course....cloned by the government to be an assassin, hence the unusual cyberware and the high grade of it.

Alrighty then slight miss under standing

*Contemplates the idea of a head spur for killer head butts*

Spurs are okay, and where they can be placed is fairly easy to judge. I'm far more concerned about players coming up with creative locations for razors.

The fluff in Cybertechnology, specifically Hatchetman's life story, indicated that putting spurs in other parts of your body does happen sometimes. If memory serves, he had a pair of spurs in one arm... one forwards as normal, one coming back out the elbow.

Logans Run... Great movie...

And the cats have three names...
