The Bear Grylls Ultimate Pro Survival Knife was created in response to demand from consumers and knife enthusiasts, who were fond of the original Ultimate Knife, but longed for an upgraded version.
Even though the original Ultimate Knife was praised for its comfortable handle, adept wood carving ability, and handy survival features, it was frequently criticized for having overly soft steel (which required constant sharpening in the field), an anemic whistle, a hard to use diamond sharpener, and a lack of visible full tang construction. You can read more about the pros and cons of the original Ultimate Knife in our full review of it here.
The Knife
The new Pro Ultimate Knife features 9Cr19MoV Stainless steel (similar in composition to American 440C Stainless), visible full-tang construction, a stronger survival whistle, an easier to use Carbide sharpener, and a new black and orange color scheme. This new color scheme is quite attractive and makes the knife easy to see when it is lying on the ground:

Blade comparison (from left to right- Gerber LMF II, Pro Ultimate Knife, Original Ultimate Knife):
A small change is the size of the ribbing on the rubberized handle. The Pro Knife has larger ribbing than the original Ultimate Knife.
Another change is the addition of a finger choil:
On the negative side, they can leave less of an edge for cutting and batoning. On the positive side, they can be an asset when needing to choke up on the blade to skin small game animals, etc., and can also make the blade a little easier to sharpen. Since the edge is not butted right against the finger guard, this area can be a little easier to reach with a sharpening stone. I've included my impression of the finger choil in the field testing below.

Whistle
The Pro Knife includes a more robust whistle than the previous version.

and the extra loops that allow for sideways carry.
The sharpener can be removed by unscrewing two small T6 Torx screws (shown in the orange area) so that it can be switched for right or left handed operation, or removed for replacement:

The Pro Knife locks into the sheath in much the same way as the original Ultimate Knife, but does away with the plastic sheath-lock that was on the older version:
To field test the Pro Knife, I wanted to focus mainly on the performance of the upgraded features. In our review of the original Ultimate Knife last year, I already covered many of the unchanged features, such as lashing the knife to a pole, striking the firesteel to start a fire, opening a can, and general wood carving.
In particular I wanted to test 1) the ability of the 9Cr19MoV Stainless to take a sharp edge 2) the edge retention of the new steel 3) the built-in Carbide sharpener to determine its effectiveness, and also to see how easy the steel is to re-sharpen 4) the finger choil to see how it might affect batoning and featherstick-making 5) the feel of the knife with the new full tang construction while using it out in the field, and 6) the improved survival whistle.
I had a friend stand 75 feet away with his back towards me. I then blew the whistles from both the Pro Knife and the original Ultimate Knife, and asked him which whistle was louder. I repeated this test three times. According to my friend, the new Pro Knife whistle was just barely louder, with a slightly deeper tone to it.
In order to test the new, upgraded steel on the Pro Knife, I did some
chopping on a small, dead Aspen tree, batoned and carved out a pitchwood
tinder knot, and made a featherstick. After these tasks were finished, I
checked the edge to see how well it held up, then used the Carbide
sheath sharpener to re-sharpen the edge, taking note of how easy it was
to perform this task.
To test the Pro Knife's ability to handle stress, as well as to see if having a finger choil would reduce the Pro Knife's ability to baton wood, I grabbed a Ponderosa Pine pitchwood knot that I cut last year and batoned and carved it into a pitchwood tinder stick.

Chopping
Below is a small dead, Aspen tree that I chopped down with the Pro
Knife. I then bucked a piece out, simulating a wilderness survival skill
to find dry wood to make fire under wet conditions. The extra weight of
the Pro Knife gave it an edge over the original Ultimate Knife when
performing this task.

Batoning and carving out a pitchwood knot for fire tinder
To test the Pro Knife's ability to handle stress, as well as to see if having a finger choil would reduce the Pro Knife's ability to baton wood, I grabbed a Ponderosa Pine pitchwood knot that I cut last year and batoned and carved it into a pitchwood tinder stick.
Even though this is just a piece of pine, the wood near the base on
these old growth mountain pine knots is stronger than oak, and often
very twisted. I've cut hundreds of them, and have seen them chip and
roll edges on heavy knives and machetes, so it was no easy feat for the
Pro Knife.
Success! The Pro Knife did an excellent job of reducing this piece into a
beautiful chunk of flammable pitchwood (also known as fatwood), with no
degradation of the edge noted.
Finger Choil
Having the finger choil didn't seem to affect the knife's ability to baton:
Featherstick Making
The Pro Knife, like its predecessor, is very adept at making feathersticks. The finger choil didn't seem to make that much of a difference in either a positive or a negative way with this task.
Steel Performance/Using the Built-In Sharpener
So how did the edge hold up? -- Leaps and bounds ahead of the
original Ultimate Knife's edge. The 9Cr19MoV Stainless has edge-holding
that's at least as good as 440C with a good heat treatment, and possibly
better. I was very impressed by its performance and was honestly a bit
surprised, as I didn't expect a Chinese stainless to hold an edge this
well.
The ability to hold an edge is a great quality, but not if comes at
the price of being hard to sharpen. I was very curious to see
how difficult this steel would be to re-sharpen, and also how
effectively the built-in Carbide sharpener would perform.
After trying the sharpener in several different positions, I found that holding the sheath as shown in the photos below was the easiest way to pull the
knife through to sharpen it. Others may have different results
of course, but this was the easiest way for me.
Conclusion
So will fans of the original Ultimate Knife find the new Pro version to be a worthy upgrade? Despite the $30.00 price increase -- definitely yes, in my opinion.
The steel is a significant improvement in all aspects, including edge-holding, ease of sharpening, and the ability to take a sharper edge than the original version.
The visible full tang construction and beefier hammer pommel also mean greater overall strength -- a critical feature in a survival knife. This increased strength inspires confidence that the Ultimate Pro can be depended upon in a critical situation.
The revised sheath, which includes a new, easier to use Carbide sharpener, along with a firesteel placed in an upright position, is also an improvement.
I like the slightly smaller, sleeker design of the sheath, including the attractive and easy to find contrasting orange and black color. The same goes for the knife, as the new black/orange scheme is more attractive than the original and gives the knife a slightly more serious appearance.
Negatives? Yes -- the whistle is only marginally improved. I'm not sure why a more robust whistle wasn't added, as this could have been a golden opportunity for Gerber to improve upon this useful survival feature. The whistle is still effective, but could be better.
Another issue is the velcro retaining strap on the sheath. The simple addition of a heavy duty button snap ala' Gerber's LMF II sheath would have made the strap more reliable, and given it a feeling of higher quality.
Also, as I mentioned in our review of the original Bear Grylls Ultimate Knife last year, I'm still not a fan of the extra large "BG" logo on the handle, and was hoping this might be toned down a bit in the Pro version. I'm still hoping that Gerber will come out with a less conspicuous, American-made version of this knife, say something along the lines of a fine-edged LMF II, but with upgraded 154CM or S30V Steel. That would be a very attractive proposition, and one that I'd certainly be interested in.
Despite these criticisms, I think this is a much improved version of Gerber's best selling knife, and one that fans of the original version will certainly enjoy. In fact, this might even be a knife that critics, who panned the original version, might finally consider a serious, field-worthy survival blade.
