Personally I hate calling it a sacrifice hand. The very words seem to indicate that you are going to lose it.
I'm not a big fan of the terminology myself, but it is accurate, as you are in effect 'sacrificing' it to save another part of your body
Yes, it may or most likely will get cut if you try to grab with it but you do have a forearm attached to it that has a larger blocking surface. Blocking first, if possible, them grabbing or locking would seem a better use of the whole arm.
Agreed about the forearm. We drill and have drilled many techs using the forearm as the first point of contact, (using the back of the forearm against the blade of course) and then transitioning from the block/parry/flow etc to the grab. Working those techs at high speed is very difficult though and takes a very long time to 'master', for want of a better word.
The unarmed hand in front can hide some of the moves if that hand has to be watched ( pokes at the eyes, ridge hand under the nose as you stab with the other, etc.) However the lead empty hand is more for blocking in most cases.
IMHO
I do see this as a valid point. The concealment of the blade or intention does make sense, but it's a hefty price to pay for the element of surprise IMO.
No we don't train that way , we have the lead hand close to the ribcage and the rear hand is resting near your throat with your chin down. I wouldn't feel very comfortable at all having the knife in the rear hand .
I think it would be too much of a telegraph when you went to strike and I like having the abilty to use the knife in the lead hand to parry thrusts or use it to trap.
We train a similar way, more of a traditional boxing stance with the blade it the lead hand. It's wierd because, although I am right handed predominately, I adopt a southpaw stance when doing knife work. It's become an automatic reaction now.
As to the telegraphing, I think that most skilled/semi-skilled knifers won't telegraph anyway. They can use the lead hand for distraction, sure, and then slip the rear hand in for the blade work.
so to answer your question, yes i train with the lead hand forward sometimes, but it's not for use against another bladed weapon. i would use it against a blunt instrument because they tend to be slower & the lead hand could act as a range finder. but it's purely academic since such scenarios are spectacularly rare.

Yes, as I pointed out in the opening post, these things just aren't likely to happen at all in most people's lifetimes and this is pretty much purely for accademic purposes, but it is interesting to see how the issue is covered in class. In the event of it happening in real life, how would that training come through, if at all I wonder. Being from the UK, I don't carry, so the chances of me ever getting into a knife-on knife are even more remote. i've face knives a handfull of times, but thankfully, only once been injured.
It's interesting that you train one way but would fight another. I find that fascinating. Do you experiment with different strategies in class that may not be applicable in reality, either sport or street etc?
People do it. That's why so many old Filipino knife masters have knicknames like "Lefty" and "Three-fingered Jose". You also see it with the untrained but not inexperienced, who have learned the hard way that this works--lead with the left hand as a target and stab hard and deep with your own knife.
There are FMAs that use this basic idea, but don't "sacrifice" per se--but they are figuring they may take a slash to give a stab.
Oh, I know people do it, that's why I wanted to discuss how popular this was as an exercise. I would like to think that we, as human beings, would not want to sacrifice something on the off chance that we could get the upper hand because of it. There's a lot of 'ifs' involved. IMO, by having the hands close to the body and using footwork, the lead hand holding the blade about half-arms distance away at shoulder height, it gives enough room for manouvre without losing a finger or taking risky chances and trying to grab. With the blade in the lead hand, you have no inclination to grab as your fingers are already occupied. The temptation to grab with an empty lead is far higher and thus, more prone to being damaged IMO.
I practice Bowie Knife. It's half Machette, half short sword, and all evil. Bad idea to try to block a 13" Bowie blade with anything not made of steel.

Now
this takes the game to a different level altogether. It's a much larger blade than the type I'm thinking of in these scenarios. Thus, easier to see where it is and what it's doing. Also, due to its size and structure, it's going to be much much easier to grab in a tustle, especially since most bowies are single edged. There's also the levearge issue where it's easier to apply disarms on a larger item. Sure, you have the advantage of a bigger blade to do bigger damage, but IMO, I'd prefer to fight someone with a large knife over a small one I can hardly even see, let alone try and control.
Thanks for all the responses so far, it's good to see a variety of different opinions too. I think we can all agree on one thing though....
