Having reached the point where i have enough new scraping projects on the drawing board, it's about time I upgraded from the mechanics set i've been using the last couple of years.
I substituted the countersunk screw for a button head because that's what I had to hand.
I now have scrapers and carbide inserts for sale on my eBay store here:
