Just got a Rebar. I was not impressed that I was not able to open the tool single handed using a "butterfly knife snap" as I am able to open the ST300 as well as the Wave models. To resolve this, I removed the rivets that hold the flat springs in each of the handles. This was done carefully w/a benchtop drillpress and a 1/8" bit. The tool now handles similarly to the ST300 (which has no closure springs). Below photo shows tool w/springs removed, as well as removed springs, and rivets.
