Nope it wont work on the spring. The end that has the bottle opener has a short pivot end and if you put the eblade on there it will sit too low and hit the spring in the middle and chip the blade. Tried it

The nail nick is also on the wrong side for that position.
If I put a pruner / eblade in one layer I take a blade spring and grind it down to the thickness of an opener spring and do it that way. Ive put that as in inner layer before that makes it less awkward to get to the nail nicks, but its still not ideal.
If you can lose the awl though the eblade fits there great.
