pitman: I gave it a 3 because the blade broke fairly easy during the hammer impacts. I think it did just fine in the outdoor test other than it is a little
to flexible for me during heavy chopping. It got through most of the tests up to the hammer and it just did not take it Compared to the k-bar heavy Bowie for example. Many of the knives have been able to take the hammer with no problem.

The CS bushman for example has no problem with this and it is razor thin almost.
Look at the CS Bushman Vibration test. I did this the same night I did the RTAK II

What happened on the Ontario is it is to flexible and it is long. You could not see this in the video because of the camera angle when I was hitting it with the hammer it was vibrating very rapidly back and forth. It just fell a part when it
bottomed out on the vice one hit and a heavy vibration was all it took.

I recreated the same conditions with the Bushman it is shorter but much thinner.The bushman took a pounding during this.

Based on all the knives I have tested I feel a knife should be able to take a hammer to it's spine a great many times before failure occurs. As many have demonstrated.

This is a toughness test so the only thing I have to judge against is the other knives and how they held up. The Scrapper 6 has raised the bar. At the time I only had the earlier blades to compare against and what they could endure.

I like the RTAK II and I would probably buy another. But I'm getting spoiled on Busee blades now. I feel it is tough enough for most general use and this may be all anyone needs.
