>>1051304I own an 78 myselfe.
I wouldn't choose the 81 since the saw is not too good and it makes fine cutting where you want to but your thumb on the back of the blade and but some pressure on it difficult.
Allover its a very good knife for the price. Its very durable i have tortured mine a lot with digging holes etc and it never let me down. And yes you have to sharpen it from time to time but sharpening it is easy. It gets dull because its a flexible and relatively soft steel but this also makes it nearly unbreakable.
So if you want a knife for real heavy usage go for it, but if you want a super good looking shiny knife that you will only use for cutting soft things you shouldn't buy it.
