That page by Randall has a slant towards serious misinformation. When I opened it I thought that it was just the Livesay RTAK page, however there is a picture of the Ontario version right in the review and the text doesn't point out the the RTAK it refers to was made by Livesay.
In regards to how it should compare to a regular machete like the Ontario, if you ignore the length issue (10" vs 12"), the RTAK should be a directly better blade, if it isn't then the edge is horribly misground and you can fix that anyway. This assumes the balance on the RTAK is similar. If it is far more blade heavy then you will fatigue faster on light work, and if it is far more neutral you will fatigue far faster on heavy wood work. The latter would make little sense considering the overall design. I would assume it is at least as blade heavy as an Ontario 12", maybe even a little more.
The reason that traditional machetes are made the way they are, is not because of the great performance it produces but simply because you can make them cheap that way - it is the worst way to grind a knife. You stamp out the profile from sheet stock, heat treat, and grind an edge - done. However with a blade with an actual primary grind you have to do much more work in making the basic shape, have to buy more material to begin with, and the heat treat is much more critical as uneven grinding can cause warping. Plus you now have to worry about finish as you probably don't want to leave it at the shaping belt fniish - 80 grit or so.
As for performance, while a full ground 3/16" blade is thicker at the spine than a 1/8" stamped machete, the edge on the full ground blade (like the Patrol Machete) will be much thinner than the edge on the cheap machete, and this is where the cutting ability comes from. For example while the blade on a traditional flat machete is 1/8" right behind the edge, on the Patrol Machete it is between 0.02" - 0.03" if I remember Will correctly. If both are ground at equal angles there will be no contest in regards to cutting ability. Plus the Patrol machete will have better action on light woody vegetation because of the hooking action, and will bind less in heavier woods because of the primary v-grind, and in fact will be stronger overall because of the increased spine thickness. Similar balance considerations as noted in the above.
The increased cost of the Patrol Machete also reflects the higher quality control of Camillus vs Ontario (I would expect anyway). The Ontario RTAK seems high in cost compared to the other Ontario knives of similar design and steel, depending on how much it gets discounted, this however just reflects having a "named" designer which always tends to bump up the price. The RTAK is a really nice basic design, it would have been nice to see Camillus produce it instead of Ontario as my experience with a handfull of their products is that the QC is horrible.
In regards to the RTAK vs the Patrol Machete, I have a PM coming and I have used blades similar to the RTAK. I would predict the performance to go pretty much exactly as DWK noted.
