Why do you think there needs to be a physical component to the blade for this? The best explanation I have ever heard of how a saber works came from Robert Brown's website. There were several explanations explored there, and the best one was that the blade consists of a long, thin, rod-shaped force field, which is rotated at zillion RPM. The outer edges are rotating so fast that they are nearing the speed of light, and are throwing off photons (hence the glow), and the hum comes from the spinning blade's contact with the air. Could such a thing ever be possible in reality? Meh... who knows? But it sounds plausible enough, and it explains why they block blaster bolts, cast a shadow, glow, hum, block other sabers, cur through anything, etc.

Bob Brown's sabre concept violated Conservation of Energy IIRC. They are briefly described as standing waves of energy in the ROTS ICS. Basically, it's the damaging portion of a TL blast in permenant ripple status, contained by a shield like mechanism.

For it to get stuck. The cutting and poking parts I don't have a problem with, I just don't understand how pure energy could get snagged on something.

I'll go find that Rob Brown site, that sounds interesting. Thanks!

MODEL SIX: virtual light produced from a spinning field surface
The idea & physics behind, this model supplied by the incredible Mr Albert Forge.
This model is similar to model five, but is FAR more solidly based in REAL physics, and is a FAR better match for the observed sabre (and blaster) behaviours! It provides a theoretical answer to ''where does the 'stuff' of the blade come from'' *AND* actually NEEDS both a fields AND rotation!

According to astrophysicist Yakov Borisovich Zel'dovich, a rapidly spinning conductor will cause the creation of virtual particle radiation at its surface. Particle production is controlled by the charge, angular velocity (of rotation) and radius of this charged conductor.

If we imagine a rod shaped charged field of atomic-scale cross-section, which is superconducting and rotating at near-lightspeed, then charge regulation becomes the control for the particle emission type and quantity. Such charged fields would tend to repel one-another (if they are of like polarity), which means the blades would BLOCK one another.

NOTE: a sabre would have to be built carefully and tuned correctly! A badly adjusted sabre would subject its user (and everyone in range) with considerable amounts of gamma radiation!.

The glow of the sabre blade consists of virtual-photons energised by the rotating field into real photons ... virtual light make real! The opaque 'thumb-thick' blade shape may be a swirl of ionised atmospheric particles (the AIR) drawn in and swirling about the core. When you IONISE a gas, you actually have a PLASMA (as it is meant by terrestrial physics) ... and this would glow JUST LIKE A FLUORESCENT TUBE (which is ALSO a plasma!) ... BUT this thumb-thick plasma zone is merely a by-product ... the REAL cutting is performed by minuscule core of the true blade ... leaving almost microscopically thin cuts. (The blade would STILL glow fiercely in even in a vacuum, as it throws off 'virtual photons - made real' ... but the thumb-thick core may not be visible.)

Such a tight rapidly spinning charged superconducting field would rend (tear) through most matter by stripping off electrons which bind atoms together. The ionized matter about the 'cut', as well as field-excited atomic movement in the localized area of the 'cut', would mimic great point-of-contact heat. A wound to a soft-tissue organic being would appear to be a microscopically thin BURN - and such a wound would usually tend to be cauterized (depending on how slowly the blade passed through - a large blood vessel cut too quickly may not be sufficiently 'burned' to cauterize).

Dense metals which have loosely bound electrons (which are free to wander about their lattice structure) would be more resistant to cutting. The 'atom stripping' effect would take a little longer to cut through, because such materials have more electrons 'to spare' before their lattice structure becomes 'torn'. Metals are also more highly conductive, and the localized 'heat' effects are minimized because the heat is carried away and dispersed through the material more quickly.

This means that even though with varying amounts of effort, a lightsabre could cut through virtually anything, some materials would offer more resistance to a sabre blade, and therefore we can now understand how Lord Vader's armour was able to ward off most of Luke's glancing blow, saving his life.

That Clone trooper reached up and grabbed the hilt when he was skewered in front of the temple.

the shearing of atomic bonds without applying said energy to shear bonds.

That and it lacks the atmospheric effects one would see if you had something simmilar to what BB describes.
