We did not patent the tip design, anyone is welcome to make third party tips.
Tips we'll have at launch: Cone, Bevel 1.5, Wedge 1.5, Point, Bevel 2.6, Knife 2.5, Knife 1.4
We made some different electrical design decisions than they did. TS-80 tips aren't rated for the power that we're putting out, so being compatible with the TS-80 tips could be pretty sketchy.
Will there be other tip shapes available?
Is the tip design patented (and enforced) or will you allow for 3rd party tips?
