on his website. All his stuff is well made and very functional. I had several classic cranks that were stripped by less skilled mechanics, over at the bike co-op here. So for me it made sense as an investment.

For the OP, I would just either find a pickle fork, or an angle grinder, destroy that Alivio crank removing it, and replace with something better. But I have stuff that is better.
