W.R. Case & Sons Seahorse Whittler Review

In a world of traditional slip joint pocket knives, the Seahorse Whittler by W.R. Case & Sons stands distinctly out. Forgoing the traditional blade shapes and handle shapes for a very unique look, while still maintaining an exceptional level of performance.

The Seahorse Whittler that was provided to me for the purpose of this review came dressed in smooth persimmon orange bone handles. The smoothness and the handle color remind me of an iced cold orange cream soda, or an orange creamsicle on a hot summer day.

While certainly unique looking, does the Seahorse Whittler from Case have the guts to be a good knife? make the jump to find out.

I have carried this Seahorse Whittler now for about two months non stop, it rides daily in my pants or shorts pocket and it has seen plenty of use. The first thing that jumps out at you is its very unique look, with a super aggressive wharncliffe styled main knife blade, and two smaller secondary blades it looks unlike any slipjoint I’ve seen in person before.

You will either love or hate the way it looks, personally, I love it. In my opinion, as slipjoints become more popular folks are going to look for pocket knives that stand out, and set themselves apart from other knives out there.

Food Prep


Due to the main blade being only 2.17 inches long, and very thick towards the end, the Seahorse whittler is not the knife that I would want to bring along with my as a food prep knife. With that being said, there are two instances that I found the Seahorse Whittler to be a fantastic choice at. One is in slicing apples, I work at various job sites throughout the day, and eat apples non stop. The thin tip is perfect for peeling, and the thick base is perfect for splitting them apart.


The second use I found the wharncliffe knife great for is taking the top off of strawberries. My almost 5 year old devours 2 boxes  of strawberries a week, and the Seahorse has seen a ton of use in this aspect. The tip of the wharncliffe is absolutely perfect for making the small circular cut necessary to do this task easily.


EDC Tasks

The Seahorse Whittler is such a useful little tool when it comes to your everyday activities. From cutting fishing line, cardboard, paper, rope it does a very good job. The straight edge of the Wharncliffe can be made very sharp( I used my previously reviewed Work Sharp guided field sharpener for the job) and without much effort can be made sharp enough to shave hair off your arm, or make mincemeat of paper and newsprint.


One of my favorite thing about traditional slip joint knives, is that in general there is no fear factor of them. You can carry them and use them just about anywhere without any second thoughts. It’s for this reason that I always have a slipjoint on me, and when in public is generally the knife I use.


Wharncliffe styled blades usually excel at this type of cutting task due to the straight blade which is ideal for cutting rope. The knife on the Seahorse whittler is no exception. Whether cutting through a single piece, or 4 pieces of rope, the blade absolutely flies through it.


For such a diminutive sized knife, the main blade packs a punch way above its weight class.


Towards the end of this review I happened to purchase our first home, and there was hundreds of cardboard boxes to break down…like hundreds! A perfect test for the Seahorse whittler to be put too. The knife is an absolute joy to use for breaking down cardboard, it slices through it with no issue at all, and can even handle very heavy duty boxes.


The only issue that did spring up, was occasionally when slicing heavy duty cardboard, the slipjoint nature of the knife got the best of it. The thick bottom stock of the knife would become stuck and when pulling it out would sometimes partially close, but once adjusted for this it wasn’t an issue anymore.


After about 200 linear feet of cardboard I had to touch up the edge a bit with my WorkSharp guided field sharpener.



I am no whittler, and in fact have absolutely no skill when it comes to the act of whittling. That being said, the Seahorse whittler is uniquely setup to excel in the hands of someone with even a small bit of skill. The main wharncliffe blade bites deeply into wood and can be controlled exceptionally well. The wharncliffe rides on both of the knifes backsprings which gives it a very robust feel, and keeps it from closing as easily on your fingers.


As well, the two smaller secondary blades compliment that main wharncliffe nicely. There is the small coping knife, and a small pen blade. The coping knife in particular is nice for when you need to make a tight circular cut, or for when you need a small knife with no point. While the pen blade excels at tiny precise straight cuts.




Final thoughts

The W.R. Case & Sons Seahorse Whittler is a game changer in my mind and should be first and foremost on your list of possible future purchases. With it’s unique design, awesome handle choices, comfortable handle and exceptionally useful blade designs you really can’t go wrong. A strong EDC knife that can go just about anywhere with you and can double as both a work knife, or a slightly thicker gentleman’s(or lady!) knife. I do wish that Case would also offer it in their Chrome Vanadium(or CV), their preferred Carbon steel, or maybe someday in a modern day “supersteel” like S30V.

    the main blade being held open by both springs is exceptional. lose the small blades and put a lock on the back.
