What do you use to leave open your klappvisor?
Possibly with pics, thanks.

Well, I believe some use a sort of leather strap that goes around the helmet to keep it both open and closed, whilst I'm sure others just have a very good visor hinge that allows it to smoothly open and close, and if your helmet slopes enough maybe gravity and geometry will do the work for you.
However I do think that trying to 'keep' a visor open is rather difficult without a modern modification, as often you see in iconography people holding their visor open, or simply removing their helm entirely.

The hinge is the key element. Too many modern repros have hinges cut like modern door hinge plates - parallel edges in the gap. If your smith files it with a tiny bevel from outside to inside on each plate, lifting the visor will fix it in place somewhat. A minor step - like a "Z" in each plate, mirroring one another - allows it to stay a bit easier. That is tricky stuff from clockwork and frankly, not seen on period examples. Mine fits by friction and drops into place with a quick nod. I would - absolutely NOT trust it to keep the visor down in close play with thrusts. I usually have the visor strapped down for anything other than demos.

Hope that helps. :)
