So I've been fascinated by this blade ever since I initially saw it. I can't quite figure out if it'd be more gimmick or if it could legitimately good.
I think one would have to play with it to feel it out but there's a simple feel test we can all do (shakehand or penhold like myself) to imagine what it would be like. Take your current blade & flip it around. Same thing pretty much.
So as a lefty penholder, I see stuff I like and stuff I have questions about.
First some pictures to point out how I see it.
Picture 1 | Left Handed Penhold. Arm extended straight in front of me with wrist straight.
and
Picture 2 | RPB with a top down view (again left handed) to help explain how I see it.
Picture 1:
So you can see when you hold a cpen or jpen naturally, the face of the blade is actually cocked at an angle a little bit as the blade handle rests on the meaty area between your forefinger & thumb. With the handle out of the way, the blade can be much more in line with your arm.
Disadvantage: This means on a FH flip, if you want the face of your blade to face the table, you actually have to cock your wrist back even more. Maybe this is a big deal for you. Maybe it isn't.
Regular FH how it's effected? I can't tell yet. I would need to feel it out but I imagine I could get along with it being about the same level as it is now.
Picture 2:
This is where this design I believe tends to shine in regards to the RPB. Normally when you hold a standard Cpen in the RPB grip, the blade is very closed and it's kinda angled down & to the left for me. For a righty it'd be down and to the right. This is again because the handle is on the meaty part between your forefinger & thumb thus angling the blade. Remove that and I get the feeling opening the blade is much easier and I'd imagine BH blocking or attacking, while I can do it with RPB, would feel more natural.
Thoughts on this? Have you guys tried it?
Okay so making it. How do we do it? Sure we could buy it but I imagine we all have backup blades collecting dust. I do. I got this Japanese saw blade thing from Harbor Freight a few years ago. I think it'd allow me to cut the handles off a blade without damaging the blade itself. It's very thin & flexible. Better ideas on this I'm open to. Once the handles are off, I'm assuming some sort of curved reciprocating saw cut in a half circle shape? Would then need to find the ball like gripper to I'm thinking glue on. Open to ideas on any of this.
