Got it. ThanksCurrently
The grind on the green handle knife is what Bart calls a Sabre-S grind. Supposed to be a slicer blade. You can get it on the model 4 and 4.5. Also can get it in either Abe-l or 3V.
The grinds on my model 4, 3V and the model 11, 3V is his traditional Sabre grind. Stronger.
You can only get the traditional Sabre grind on the model 11 and only in 3V.
