Specs: Scrap Yard Scrapper 6 Halloween Night 2007
Steel: SR-77
Blade: Length: 6.5"
Overall Length: 11.5"
Thickness: 2.75"
Hardness: 58-60 Rc
Handle: Resiprene C
Summary of test:
Cutting: The knife was donated and was slightly used. I touched up the edge on a diamond stone. The Scrapper 6 did fine peeling the apple. It did not do well on the 10,000 pound webbing. I test the factory edges most of the time. Cutting performance can always be improved with some work.
Batoning: I had some trouble splinting a 4x4 I had to pound it hard to accomplish the task. The knife is very solid for this type of work.
Chopping: The Scrapper 6 performed fair at this but not as good as the A1.
Tip work: I was able to dig a hole through a 2x6 no tip breakage occurred.
Sheet metal penetration: I stabbed the tip into some heavy gauge sheet metal breaking the tip off. The tip is fairly thin on the scrapper 6.
Hammer Impacts: I hammered the edge into a 2x6 first no problems occurred during this.
Concrete: I chopped a huge concrete block the same stuff used on the GI Tanto. This is some very tough stuff it contains large rock. The edge dented first then chipped. the edge took on a lot of damage more then the GI Tanto did. I hammered the edge into the block attempting to split it more chipping occurred and a tear begin to develop. No blade failure at this point.
Concrete continued: I hammered the tip into the same concrete breaking it apart. More chipping occurred on the damaged tip from the sheet metal test.
Body weight test: I placed the knife in the holder about 1" for the handle. and applied all 225 lbs bouncing on the knife. It is very strong and stable. I moved the knife out of the holder about 1.5" again applying my weight and bouncing. The Scrapper 6 held up to this test even with all the edge damage and the tear from the concrete test. No blade breakage occurred. The Scrapper 6 is much stronger then the A1.
Flex test: I used a torque wrench to measure the foot pounds and a scale to measure the degrees. I got up to 100 foot pounds and about 35 degrees before I broke my torque sleeve. The knife did not break during this and returned to zero. A new tougher sleeve will have to be built. Live and learn.
Metal on Metal: I hammered the damaged edge extremely hard using the 3lb steel mallet the into a piece of 1/8"x 1.25" flat mild steel stock. the Scrapper 6 cut all the way through it tearing/chipping the blade some more. No blade breakage occurred.
Side Tang impacts: I placed the blade in the vice and hit the side of the handle with the 3lb steel mallet. I hit the hell out of it trying to break it but I could not. I gave it everything I had and it would not give. The tang/blade bent only during this. Only minor damage occurred to the Resiprene C handle.
I put it through all my tests at it and it was still together. I declared the Scrapper 6 a survivor of the destruction test. The first one to do so.
However this is a destruction test and it ain't over until it's destroyed.
Metal on Metal: I hammered the non damaged edge portion cross ways in to some 0.120"x 1.50" OD mild steel tubing almost shearing it in half. A large section tore out of the blade. This is incredibly brutal for any knife to survive but the scrapper 6 did. It's still not over. I repeated this using the undamaged edge portion(belly) of the of the scrapper 6. I was almost able to cut all the way through the tubing before the blade fully broke at the section containing all the damage. One super tough and resilient knife.
Overall: This was the strongest toughest knife I have tested yet out doing all others. Cutting performance was on the weak side with the near factory edge but this can be improved with some work. I was told by the owner of the knife it comes with a thick edge so the user can sharpen it to there liking . The SR-77 steel was very interesting in the way it performed. There was a combination of chipping, denting and tearing. It has a lot of flexibility and strength and toughness even with major edge damage.
The term hard use knife defiantly applies to the Scrap Yard Scrapper 6.
