Hi Mervin,
I apologise for my flippancy.
eBay is full of 45's for sale - but prices vary considerably.
A couple of hundred bucks will buy you a starter,
but the reality is you will need to add that again for a sharpen and set,
with a new bottom blade.
I hope your new book does well when released on 9 December.
I hope the stories have inspired you for an 'action' story.
All very childlike.
