The two ends of the spring are different so the blade on the ‘wrong’ end of the spring will sit a bit further down into the knife. It’ll probably work ok - certainly worth trying. You might find that there’s not enough width for both blades if the blade layer is next to the scale. Placing the blade layer in the centre will give them a bit more space.
Great thread for a new, would be SAK modder like myself. Reshaping the tools to another use is something which I had not thought of.:-)
