I think the Street Scrapper 4 or Scrapper 6 would both work well and survive the abuse.

These knives perform.

Look at the guarantee.

The reason you can't order a knife is that the company sells out a production run very quickly.

The Street Scrapper 4's sold out in about 3 days. They were popular because of their Infi steel. They were a one time deal, if you want one, try the exchange on Blade forum, be prepared to spend $200+.

The Scrapper 6 sold out and we are waiting on the next production run.

The Dog Father is due to be released very soon, they should sell quickly.

Another option is the Swamp Rat Howling Rat LM. Swamp Rat should have more available soon but presently they are sold out.

Lastly you might want to look at a Busse Game Warden or the new Badger Attack Tac. If you can wait, the Badger is a lot of Infi for the money. I just bought a Busse Muddy Skeleton Warden on the Blade forum exchange for $180, so they can be had.

If you are looking for a knife that just cuts, a Busse/Swamp Rat/Scrap Yard might not impress but if you want a knife that can chop through a cinder block without breaking and still cut, you have found the right place.
