Wally's wackker

When W was younger, he was for a while a maths teacher.  He was quite a joker, and apparently used to threaten to wack his pupils if they were underperforming.

One group got together and presented him with Wally's Wackker at the end of the year.

I love the detail that has gone into it, including shaping at the "safe end" with labels for the fingers and "thumb finger".  It's quite a lethal implement, I don't think you could get away with carrying it around a school these days!

I'm posting this for Silly Saturday.  I don't normally do blips for the Challenges, but was upset to read that Admirer had died so suddenly, and wanted to show my appreciation of her contribution to the site.
