Case Seahorse Whittler Black G-10 Knife Review

Out of the entire Case catalog, no knife stands out to me quite as much as the Seahorse Whittler. With its unique primary blade and unorthodox proportions, I saw it and just had to test it out myself. After a number of months of owning it, it’s actually become my main around-the-house everyday carry. I really don’t see myself every parting with it.

Very few knives have such an interesting sense of proportion, as the Case Seahorse Whittler. It really has a unique place in my collection, and whilst some may consider its styling brutish and too unorthodox for a Case knife, I think it straddles the line between function and aesthetic beauty very nicely. It definitely has some attractive visual flourishes, like the nickel silver bolsters or the slightly contoured and polished G-10 scales. Those features give this knife a sense of identity beyond its function as a folding wood carver/whittling knife.

Much like Spydercos or Marmite, you will either love this one or hate it, and there’s nothing wrong with that. When you try to please everyone, you usually end up with a very mediocre piece, pleasing no one particularly in the end. I’m glad Case decided to carve it’s own path out for the Whittler (yes, pun intended).

The Case Seahorse Whittler’s unorthodox styling doesn’t mean it can’t function as a perfectly capable everyday carry slip joint. In terms of size, it hits the perfect balance between too small to be useful and absurdly large. At 10.16 cm (4 inches) closed, it’s pretty damn perfect, at least in my opinion.

With that said, like 99% of traditional slip joints, the Seahorse Whittler does not feature a pocket clip, so size is important as it will be riding in the bottom of your pocket.

The Case Seahorse Whittler’s primary blade basically defines this slip joint’s core function. It’s quite literally designed to be a whittling knife from the ground up, with a very aggressive 5.5 cm (2.17 inch) Wharncliffe blade that was machined from a 3 mm (0.12 inch) thick slab of Tru-Sharp stainless steel. This baby ain’t exactly subtle, and definitely doesn’t evoke a conventional blade design philosophy. Frankly, I think that’s a damn good thing, as I feel any innovation in this industry is ultimately beneficial for the end user. In this particular instance, I think Case did a bang up job and not only is the Seahorse Whittler a firebrand design, but also a high performing one.

The Case Seahorse Whittler comes with 2 other smaller blades. I can’t say I have ever been a huge fan of spurious additions to what I consider to be single-use tools, but in this case, the primary blade is so unorthodox in both style and function that I think it’s nice to have the option for leaner, smaller, and consequently more maneuverable alternatives for everyday tasks.

The tiny spear point is very lean and reminds me of the blade on a Victorinox Classic; very traditional and utilitarian in nature.

The third blade is an odd jack/coping knife design with a pronounced swedge cut from the top on only one side of the blade. The swedge exists on both of the tiny blades (on one side only) so that they don’t get in the way of the primary blade when the knife is closed – very impressive and elegant solution. In terms of cutting performance, this blade is very nicely ground and cuts above its weight class.

Beautiful design and very unique. I daresay no knife could be a true comparison to this one. If you like it based on aesthetics alone, I would snag one up soon, in case Case eventually discontinues it. I very much doubt you would ever be able to find an alternative.

Here you can see the piece the resistance from its most interesting angle. 3 mm thick is not actually very thick for a modern folder like the Spyderco Para-Military 2, but for a 4 inch slip joint, it’s pretty shocking. But based on looks alone, I absolutely love the thickness!

The back spring is sandwiched by two brass liners, as is common in traditional knives. The contrast in colour is interesting and definitely adds something special. That makes up for the added weight, which stands at around 2.6 ounces (73.71 grams). By no means a featherweight, but it’s not unwieldy either.

The “walk and talk” is very nice, with nice clean snaps and smooth deployment. I will say that the 90 degree stop is a bit mushy for my liking, not as nice as the one on the Swayback Gent, but that seems to be a product of the design (no notching on the tang of the blade for the blade to rest at 90 degree), not a manufacturing flaw.

The primary blade is ground acutely with a very even full flat grind. In time, I may convex the edge to turn it into what could possibly be the best casual trek folder ever conceived, but we shall see. As it stands, the blade performs extremely well for all wood-based tasks, and as such, I am in no hurry to permanently modify it.

Ergonomics are natural with full four finger grip. The bolsters are fully contoured, making the transition seamless. Very nice and no abrasive hot spot.

Carving is what this slip joint does best. The blade bites in and cuts remarkably well. The Wharncliffe design allows pressure to be applied evenly, and for tasks like notching and carving, I can’t think of a better folder in my collection.

Very clean cuts and pretty much perfect for making traps and snares. By far one of the best options for those of us who want to go for a quick evening trek and don’t want to lug around unwieldy equipment.

The general fit and finish is pretty much perfect, as is the centering. I love how the primary behemoth of a blade slips in between the other two tiny ones. Very little room for error, and yet no instance of the blades rubbing against each other. Very nice job Case.

Case knives have been around for a long time (since 1889 in fact!). Instead of remaining stagnant like so many of their competitors they have impressively embraced modern materials and performance ideals, all whilst retaining their core identity and traditional roots.

The Case Seahorse Whittler in black G-10 is the perfect example of that evolution in materials and blade design. It offers a surprisingly high performance folder that can take on pretty much any other knife, regardless of price range, in its intended function. The Seahorse Whittler does so with a sense of style that is unreservedly Case. It’s hard to find something to criticize about it, as no other knife in this price range offers this level of performance for its given purpose. Would I prefer a premium edition with 154 CM steel? Hell yes, but it’s clear that the price would also have to be increased. Perhaps Case will offer a sprint run in the future if enough of us clamor for an upgrade. Until then, I am quite content with this superbly constructed folding whittler.
