I have not actually thought of modifying the wave, mainly because I think it is well designed as it is ( although I wish the blade would stay sharp longer...)<br>How did you add a compass to the wave? Glue it onto the handles?<br>I like all the neat stuff on the SAK too ( I have a swiss champ and now a workchamp too), but I think that if you really want more stuff in your package, it would probably be easier to get a better sheath for the wave or modify the sheath to hold more stuff.<br><br>I have this fear of my (unprofessional) modifications either affecting the functionality of the tool or screwing it up big time!<br><br><br><br>
