Interesting to note that the printed link (included with the WE60) to the instructions, is redirected to YouTube and a series of ten instructional video's by Elizabeth.

I see the guide rod retention screw has already been altered in the released version to a knurled head, yet Elizabeth says it needs to be tightened with a screwdriver?
Even though there is no room to fit a stubby flat blade screwdriver into the slot correctly (distance to the clamp too short), she uses it sideways which has damaged the screw as it's tapered. (video 10, 1:31)
Of course it's also another tool you need to buy and carry with the kit.
I'm betting we will see a socket head or hex screw coming soon.
Edit:
I did notice in 000Roberts' review he said this
"Future WE60 Sharpener Units will have hex heads on the Angle Slide Locking Screw and Delrin Guide Rod Retention Screw sized to 11/16” and 7/16” respectively so that they can be operated with standard wrenches."
So I guess we will need to buy and carry a wrench?
