exactly mate, I have no idea why some companies do not give thought to the pass through. The 037 isn't too bad even though it has no cut out for the pass through but I have found some knives (Maxace Amber II is a perfect example) desperately need a cut out as it is very difficult to access the lock properly.Re the pass through - it's weird why they do that. Why do they do a cut out both sides essentially cancelling out any pass through? The only thing I can think of is that it is not even pretending to be a pass through, but contoured for your index or 2nd finger. I would have gone level one side, pass through on the opposite side.
