What is the proper definition of a layer on a SAK?
Is a layer defined as the space between two liners?
Or is a layer defined as the number of tools stacked vertically between two liners?
It is clear that two tools, each taking half the horizontal space between two liners, is counted as a layer (e.g, the non overlapping can opener and cap lifter at opposites ends of a space between two liners, or the partly overlapping small and large blade at opposite ends, and and the non overlapping inline Phillips driver and the magnifier opposing).
But on my Vic Champion Plus, a wood saw and a fish scaler are stacked vertically between two liners. Is this considered one layer, or two?
