I've had 2 Gerbers and was NOT impressed.
This one extends out of the handle. It won't stay extended. You have to lift it out of the wood on every forward stroke or it will retract into the handle.
This one has a button to push to open or close the blade. The button broke the 1st time I used it.
RC, I've never used the top version, but I believe you... not a reassuring looking design.
The second, the exchange-blade Gerber; I had an early mfg'd one. It lasted a LOT of hard use for over ten years, then broke (the button). I've read the early ones were well made, then they were slightly redesigned, mfg'd elsewhere, and the quality went down hill. That reputation, and its weight, kept me from buying another one.
I've still got the sheath and extra blades, but the saw is in the landfill. Pretty sure I got is somewhere around the early 2000's.
