You can make one if you find a reasonable quality screwdriver with the properly sized round shank (1/4 inch or 5/16 inch, depending on which size you are after) then cut off the tip of the driver leaving the perfectly round shank and then the tricky part - getting a square across grind to form the tip (lots of patience and knowing how to keep metal cool from losing its temper, unless the tool is made of M2 HSS or better - perhaps a standard HSS drill bit may do as well..but then you need to have enough non-fluted shank to craft the driver from...) You can buy HSS tool blanks on amazon of course - reason I specify HSS - preferrably M2 or better - You can grind it to blue pretty much, but it won't lose its temper, unlike carbon steel where grinding it blue ruins the temper of the steel.. Anyhow if you got the time and the patience (and the grinder) with the right steel it is easy enough to fabricate and grind your own tools - but by the time you get done buying the HSS steel or quality screwdriver, you may as well splurge on the specialized Briggs tool if you can find one available (I think Briggs discontinued them long ago, but you may still find em used or NOS on Ebay.)
