Welcome Mick.
You are TOTALLY in the right place. There are nothing but the tough, workhorse knives you are searching for at Scrap Yard. All of the Bussekin for that matter.
I believe the Scrapper 5 Limited Editions are still for sale made from the INFI (Busse Combat proprietary steel).
You can't go wrong there. Price to performance ratio really is amazing for anything coming out of the Scrap Yard.
