Building a separate handle is a fine idea, but it's not a SAK mod. I know I'm not good at making things look beautiful and polished like you do, but I think I am pretty good at trying different things and finding creative solutions to stuff that other people might not think of. I do find it interesting that when I did come up with a simple solution to address your criticism, you simply found more things to criticize. This makes me think that I could probably never do anything to make you happy.I always find it educating and entertaining to read about builds and trix, even crazy ones I just found this one a bit hard to appreciate, since I would need extra tools to attach this to the SAK... Part of the charm with the SAK´s (for me) is that it should be "the multi-tool". For this to be useful I would first need a SAK with the modified opener, a sawblade, separate screwdriver, and a bag with the screws and mounting plates. That´s a lot of extra stuff to carry. If you would just build a handle for the sawblade instead, you would just need that and your SAK (without the modified opener). I do not have access to a full workshop with tools, but if I did, and it was my build idea, I would make the stabilizing like a box with open ends and a sliding lid
I find that whenever you try something different, there's always going to at least be one or 2 naysayers popping up to tell you exactly how and why it's bad. Everyone has an opinion and everyone has a preference. I respect your individuality and your preferences, but they're for you and not me. I won't argue with you, I will simply encourage you to take what I did and try to make it better if you can, and that goes for anyone else too. Try to come up with your own solutions and/or improve on existing things that have been put forward by others. For example, another poster has said they are now contemplating trying to get a 3D printer so that they can create their own design for a clamp style jigsaw adapter. That's the kind of thing I like to see: people coming up with their own ideas and sharing them freely. I hope they succeed and I hope that I can eventually get my hands on a few of their 3D printed jigsaw adapters.
