Some manilla rop...a Busse...an RTAK...

Hello all! I was at the building supply store today trying to figure out how to fix my %$#@ing window when I discovered a big pile of 1/2" manilla rope. Finally a chance to do some true rope tests! I bought 35' and headed home to play.

I decided to play with my two favourite knifes, a Busse #7 and a Newt Livesay RTAK (I'd have included my BM-E but I don't have it yet). Firstly, let me say that the RTAK has quite a length advantage over the #7 so one of the results is not surprising. Secondly, both knives have a 24 degree angle, sharpened to 3000 grit and stropped.

I began with the hanging rope test. The RTAK did a better job here and I figure that's because it's a thinner stock (3/16") and a longer blade (more of a stroke). The #7 bit deep every time but only once did I get it go all the way through. All cuts were done with about 1-1/2' of rope below the cut point.

I then took all the sections of rope and started cutting them into small sections. First by chopping at them and then by laying the same section of the blade on top and leaning down. The results here were interesting. The RTAK chopped as well as the #7, but required more force when simply leaning on the blade. Also, you felt that the #7 was making a cleaner cut with less effort.

After my 35' of rope was reduced to about 20' I checked the edges of both knives. They were still razor sharp although the #7 seemed to feel sharper to the touch and could push cut paper with ease, the RTAK could push cut, but not as well. A few strokes with a loaded strop and both were terrifyingly sharp again.

I'm not sure how scientific all this is, but boy did I ever have fun out there!

The moral of this story? BUY A BUSSE! BUY IT NOW! CALL PRISCO!

Nice job Johan, but you've still got 20' of rope left to go. Let's get cracking

Johan :

I would assue the RTAK has a much thicker edge profile. My RCM's edge was much more obtuse than the Battle Mistress.

They were still razor sharp although the #7 seemed to feel sharper to the touch and could push cut paper with ease, the RTAK could push cut, but not as well.

1095 is a soft carbide steel, the edge wears really quickly in relation to tool steels unless they are too brittle (not much of a chance of that here though)as 1095 is decently tough and ductile if not overhardened.

I'm not sure how scientific all this is

It is horribly unscientific, as Cougar descibed some time ago no where did you mention wearing a white lab coat.

Looking forward to your impressions on the Basic vs the full INFI blade.

Bronco-Thanks for your compliments. Sorry I let you down and didn't chop up the rest of the rope.

Chip-I'd like to say the other 20' for my BM-E but I had so much fun today I'll bet it'll all be gone by Saturday.

Cliff-The edge profile on the RTAK is thinner than on the Busse, I'm not sure why it felt different. When I get the full INFI I think the only way I will be able to compare the two is with a very specific test requiring little wear. Instead of seeing which knife can cut the most rope for example (I can't afford than much rope), I'll probably see which one can cut the most rope and still push cut, or something like that. As for the scientific aspect, I SWEAR I'll wear a white lab coat (I have one) the next time.

 
Interesting, the Busse has a more obtuse profile and went through with less force.

Logically, you wouldn't think it makes any sense, but those were the results I got. I plan some more tests later on and I shall see if the results continue to be the same.
