ThomasKuederle I’ll answer this in two ways:
Short answer:
Could Victorinox put a hex hole in the tool? - Yes.
Could you put a hex in the tool yourself? - Maybe.
Is it practical or something that should be done? - That’s up to you to decide.
Long answer:
It’s pretty hard to drill a hex hole. If I’m correctly understanding what you’re asking for.
Sorry in advance for being a wet blanket. I’m kind of blunt as I do really know how to sugar coat things.
Are you talking about something Victorinox would create in production? During initial tool stamping would be the only time that would make sense to me. Then I’d also question how strong the tool would be if they did. In my view it’s a really poor position to use a bit driver. It needs to be inline or you can only use it when there’s enough room to swing the tool. Torque is so over used as a reason to have screw driver tool on a knife operate 90 deg to its handle. It’s really BS because these are little screwdriver bits not sockets people would be turning. They break or strip out very easy with an inline driver with very little torque. It’s really pointless because there is no screw head made that can handle that kind of torque from an 90 deg driver and quite frankly any bit either but I digress. If there was a hole for a hex bit in the tool you’d have to try to hold the bit in position at the same time as you swing the tool? Not very practical at all for me. Then there’s that fact that the force on the sides of the bit while turning is only on the tool width portion. Not good for the bit or the tool.
Basically there are only a couple of ways that I know of to make a small hex hole in a small tool like that. It’s critical how precise the hole is and that wouldn’t be easy to do to the tolerance actually required. Could they even be done after the tool has been hardened? Possibly but it would be hard on the tools used for the cutting. Using a broach to cut a round hole into a hex is about the most precise way that I can think of. I have made a broach to cut a round hole into a square hole with just hand tools before. I won’t outline that here. Would it be possible to do that with a hex. I don’t know. You have two additional angles to cut out of the round shape. I do have thoughts on how I would try to do that.
The second way I can think of that someone could do from home is kind of obvious. To hand file a round hole into a hex. Very hard to do precisely and it would take hours and be very hard on the super small triangle file itself.
There are other ways but they are very expensive and the tools aren’t very common and I quite frankly I question if the precision would be adequate. Things like a water jet machine or an Iron Worker hydraulic press with appropriate dies, etc.
So you decide if it’s something you’d want to do yourself. We all like different things. I do understand that. I personally wouldn’t like the look of it and I’d never use it. I’d just buy a bit holder in the shape of a small hollow bit screw driver and be done with it. To me the tool looks very premium now with the uncluttered tools and the Alox scales. This is a case of less is more to me.
