Description

The Case Yellow CV Slimline Trapper is a work-ready knife, built for use all day long. The Slimline Trapper is a thinner version of the Trapper and only includes one blade. This durable folding knife features a yellow synthetic handle and the clip blade. The bright yellow handle color will keep this Case Slimline Trapper easily within your sight. The Clip blade is commonly used as a multi-purpose blade and preferred for detail work. This knife is constructed with our chrome vanadium (CV) steel. Some knife lovers will settle for nothing less than chrome vanadium blades, since this special formula of alloyed steel is the “original” Case blade steel. Case chrome vanadium blades are known for their edge-holding ability and easy re- sharpening. However, they are less resistant to rusting, pitting and discoloration than stainless steel. We recommend keeping a thin film of oil on the blade to maintain the finish. This ensures that your knife will be around for future generations to enjoy.This pocket knife is suitable for everyday demands, hunting, or the outdoors. Comes conveniently packaged in a box. Made in Bradford, PA, USA from domestic and imported materials. From the Manufacturer The 031 Case Slimline Trapper features Yellow Synthetic handle and traditional chrome vanadium steel Clip blade. The Slimline Trapper measures 4 1/8" closed and weighs just 2.3 oz. It's no wonder this knife has long been a favorite. With a 3-1/4-Inch blade, this is a real workhorse, but the slender handle makes it fit comfortably in a front or back pocket.

    • A great knife to have in your pocket
Color: Yellow CV Style: Chrome Vanadium
Gibbs Rule #9: Always carry a knife. I bought one of these decades ago, and it was my favourite pocket knife. One day I decided not to carry it because I never really used it. That day I had an electrical problem with my motorcycle and I needed a knife. (I was able to use a P-38 can opener that's on my keychain -- still, 30 years later -- to strip the wire.) Since then, I always have some sort of blade. I seem to have misplaced my original Case WR XX Slimline Trapper (it's around here somewhere), so I bought a new one. I always put it in my pocket when I go out. I've even used it a couple of times. The blade has a sharp point, which makes it useful for detail work. Having only one blade, it's compact and elegant. The yellow handle is very attractive, and somewhat 'retro'. I have many Victorinox Swiss Army Knives, several of which have been in the pocket rotation (and one lives on a lanyard in my backpack). But my Slimline Trapper is the knife that goes into my pocket every day. ... show more

    • Case is the best!
Color: Brown Style: Stainless Steel
The media could not be loaded. This was a gift for my stepdad, and it was absolutely perfect. The quality is excellent—very well made, sturdy, and looks even more beautiful in person than in the photos. It feels high-end and thoughtfully crafted, not cheap at all. He loved it, and it made for a really meaningful gift. I would definitely recommend this to anyone looking for something special and high quality. ... show more

    • Takes me back.
Color: Yellow CV Style: Chrome Vanadium
I had an old trapper when I was a kid. It was my first knife that wasn't a cheapo barlow with plastic handles. I don't really know what happened to it- I can only assume my dad palmed it at some point during the blur that was my teenage years. I really loved that knife right down to the stains on its carbon steel blades. The spey blade on that knife was useful to me in that i didn't sharpen the knife nearly as much as I should have (and I can't have been good at sharpening knives anyway at that age) so I had that 'second' blade, which I practically never used, for tasks that required a more honed edge. That knife was my "rosebud" and so I can't really present an unbiased review of the single blade version for that reason. I just up and decided to buy a new trapper one day, but with only one blade this time, and a sexy looking drop point of a blade at that. Because I grew up, and partly that means that now I can put the devil's grimace on just about any knife edge. Particularly a hi carbon blade. Also, being an adult means not automatically gravitating toward the pocketknife with the most blades.. The slipjoint is nice and tight for the size of the knife. The look, well.. we live in an age of images, so I'll just say the design fits my hand perfectly, and is a nice texan cousin to my stainless laguoile. Both very elegant knives.. The slimline wouldn't be much of a workhorse, the blade being as slim as it is but it's terrific for those tasks becoming to a distinguished gentleman. or a surgeon.. Or really any performer of 'indoor' tasks.. Also, I have to mention that Case is just the best for presenting sharp blades. I remember this being true of my childhood trapper as well but Case blades come sharp! I recently bought two Kershaws and a CRKT and this little champ came sharper than all ! Good quality made the same way for over a 100 years: you can't beat that. ... show more

    • Really well-shaped handle and blade
Color: Brown Style: Stainless Steel
First, let me start off by justifying why I deducted one star: the synthetic scales are just ugly. They don't look as good as they do in the photos. They are just a flat, dull brown. On the other hand, if you're going to carry this in a pocket with keys banging against it, those Delrin scales are not going to show any wear. So Case is right to name some of their knives (the blue ones) with synthetic scales "Workman Series." A workman will not care about this, but someone who really takes pride in his knife will. The build quality is good, not great. These days, Case knives may have gaps between the liners and backsprings. This in no way effects function, but it is a shame to see; as they weren't like this 40 years ago. The grip on this knife feels like a slim steak knife, when I have it open in my hand. Although it is called "Slimline", the spine of the blade is actually pretty thick. As always, Case's surgical steel takes and holds a great edge. Regarding pocket carry, this is good in all but dress-type pants. While it is a bit longer than I like to normally pocket carry, it is both thin and narrow. Sometimes too, it is just nice to pull out a pocket knife and have a full size blade to work with. I don't do a lot of heavy duty cutting of rope or anything, but I do use my pocket knife to peel and cut up fruit, and for this kind of job, this knife excels. A note on this model compared to the conventional trapper pattern: this one is more comfortable in use, because when the blade is open, the handle is bare. There is no second blade pushing into one's fingers, while the other blade is in use. So my closing recommendation is that if you want a knife you'll be proud of, and you like this design, pony up another $15 or so and get a bone-handled version of this knife. If it is going to be mostly a work knife, this one will do the job for you. ... show more

    • Beautiful knife!
I purchased this for my son. I like it so much, I almost kept it for myself. He loved it. I have heard Case is having some quality control issues but you would not know it by this knife. Too nice to use daily. More of a gentleman carry in a nice leather sheath for all to see.
