In 20 years of playing guitar, I've never heard of this. The description would apply to Travis picking which uses only the thumb and forefinger (variations use additional fingers). Using the two fingers gives more of a point--counterpoint effect than can be achieved with just a single finger, and makes syncopated accompaniments in country/folk/blues styles very simple to execute. The Fleetwood Mac song Never Going Back Again has a very nice example of an advanced Travis-picking style (incorporating other fingers and arpeggios and rolls and flourishes).

A similar technique is used in the Beatles' song Blackbird. In this song, the thumb and middle fingers pluck a bass note and a 10th (octave+third) above together, and then the index finger plucks a note in between the other two on the backbeat. This third note then determines the chord which was suspended on the primary beat. It gives an effect similar to syncopation, although the backbeat is not given any dynamic emphasis.

But t The name Scalpel suggests that folk-blues may not be the appropriate style from which to interpret this. The word is more suggestive of Heavy Metal or a sub-genre like Speed-Metal or Thrash. If this is the case, then it probably refers to a technique using a pick where the hand is rigidly anchored to the bridge of the guitar (best with a fixed-bridge electric like a Gibson-style without a tremolo). This way, you can still control what you're doing sonicly whilst bouncing wildly around the stage. Since the hand and forearm are rigidly anchored, the muscles of the fingers have to do all the work plucking the strings. This limits your dynamic range, but that is not so much of an issue in these styles.

After watching the video in the linked thread from the comment, this last guess is closer to the mark. It's a tremolo technique apparently. As PD in the first video comments, being rigid will lead to fatigue. And allowing more muscles to help will distribute the effort. From a Hatha Yoga perspective, even your left big toe should be doing it's part to help: gripping the floor ever so slightly to counterbalance the other muscular forces.

This video appears to lay-out the exact differences among the different tremolo styles. Scalpel apparently involves just the thumb and forefinger, as you had already gathered, with the hand anchored but not rigid.

There are a number of conflicting physical phenomena that make it difficult to find a comfortable balance. For a nice tremolo picking, you want an even, sustained sound.

If you choke-up on the pick and allow only sharp tip of the point to attack the string, the friction will be low and less energy will be lost into the strings. Less friction means less sound, less oscillatory power is being transferred to the strings. Also, again since little energy is transferred, it will require some musculatory action to stop and turn around.

If you allow more of the pick to attack the string, you may find a sweet-spot where the energy lost from the movement of the hand is exactly what your hand needs to do the stopping. Then you can factor-out that muscle action. Your fingers and wrist don't need to expend energy on the slow-down turn-around. As a baseball analogy, you don't try to land on home plate, you aim for a spot past the plate so you don't throw away your speed, you pass the plate at full-tilt. I suppose the analogy doesn't really hold because our poor ballplayer is obliged to trip over the plate every time.

Ehrm. Does that make any sense?

The video also talks about changing the angle of the pick so there's more edge. This gives a scraping, shimmering effect somewhat evocative of a Sitar which uses a wire plectrum striking the string edge-on. That's friction. It pulls energy out of the motion, so adding this effect will require more expenditure from the muscles to compensate.
