The basics

Buck’s Slim Pro series is basically a modernization to the well-known 110 and 112 models. The 110 and 112 were originally designed to provide something similar to a fixed blade in an envelope, but they have advanced a lot since then.

Slim Pro series has no scale material or heavy brass bolsters. Instead, it offers unlined micarta and G10. This knife is more up-to-date thanks to the addition of a pocket clip and a thumb stud that allows for a one-handed opening.

The Buck cognoscenti will note that the blade shape was altered. This included straightening and lengthening the swedge to create a stronger tip.

The last difference between the Slim Pro, 110 and 112 is the switch from Buck’s 429HC to S30V steel.

Fit and Finish

There were many complaints about vertical blade play when Buck introduced the Slim Pro series. These were not cosmetic issues, but actual problems due to the new manufacturing methods.

Buck created a slim-pro with a hinge pin that is riveted, in contrast to the original 110 and 112’s pinned construction. Insiders say that this required some adjustments and that a few were not up to standard

My Slim Pro 112 works well.

The back spring in the closed position is barely flush. My fingernail can grasp it for a moment if I try. This might seem unacceptable to a collector; however, it is not a problem for me as a user.

Do you want to see the proud back spring of this family?

The blade and back spring are flush in the open position.

Micarta scales were flawlessly executed by me.

The blade grind is perfectly polished and centered.

On either side, very slight gaps can be seen.

If I hold the knife tightly and push hard, I can feel a tiny bit of vertical blade play. Lock-up is extremely solid and light force does not produce any.

This knife has been with me for six months and I am impressed.

Comfort and grip

Like many others, I do much more than just fish outdoors. I enjoy hunting, hiking, and camping. It’s not always what I feel at home on the couch or at work that makes me stand out in the field.

I have found the knife’s scale shape and material to be a good grip even in wet, bloody, or slimy conditions.

The 112 Slim Pro vanished in my hands while I was butchering and skinning meats. Instead of worrying about the tool, all that mattered was my work. That’s the greatest compliment you can pay any knife: to disappear into your work.

This is also true when it comes to cutting bait and cleaning fish.

Pocket clip

The 112 Slim Pro’s pocket clip is large, sturdy, and wide. It allows the knife to be carried low in the pocket.

It is very secure and has never failed to retract in my six months of EDC.

It’s still easy to grab with one hand.

Locking, opening, closing, and closing

Buck is an expert on the 112, so it’s no surprise that the thumb studs are located where they can give you the most leverage, while also keeping your hands clean of any cutting or slicing.

The blade can be a bit stiff to open, which is an acceptable compromise when you’re pinning micarta that is not lined. I believe that the pin must be tight to minimize blade play. This will compress the micarta scales against it.

It takes more force to open and shut the Lockback than other locks, and definitely more than standard liner locks.

This problem is exacerbated by wetness, when micarta appears to swell slightly, causing even more friction.

However, it was easy to open the knife with just one hand.

It is easy enough to close the knife with two hands. You can also close it with one hand by inverting your grip, pressing the lock, and folding the blade against your leg.

This technique can be dangerous so it is important to exercise caution. As you can see, the slight choil is effective in preventing injury.

The lock opens with a loud snap and has never had real-world problems with slippage or disengagement. It is easy to open with my thumb and secure when loaded.

The lock is located to the rear of the handle. This ensures that it can be easily grasped and not disengaged accidentally by serious pressure.

Sharpening and Care

Marta is a tough material that can absorb small amounts of liquid.

The 112 Slim Pro’s Lockback makes it more difficult to clean than an open-framed liner lock. The interior of the knife.

It seems that a simple rinse in warm soapy water will suffice.

T S30V is extremely corrosion-resistant and I have not had any problems with staining or getting rust off of it.

This knife has been used in saltwater, cutting bait, fishing lines, and rope. I have also removed urchins from the bottom and made limpets without rocks. The knife was left wet for many hours without being rinsed or cleaned. There was no sign of corrosion. AUS-8 was also put through the same test. I noticed pitting and corrosion within a matter of hours.

Although S30V is well-known for its edge-holding abilities, many users complain about how difficult it is to sharpen.

Buck’s Bos heat treat brings out the best in this steel. I find it holds its edge much longer than Ontario’s 8AUS-8, Buck’s 420HC, 1095, and 440A. Buck claims that the steel is hardened to Rc 59.5-61.

Chipping has been easy for me, and that is something I cannot say about any “super” steel.

Spyderco Sharpmaker is my go-to tool for sharpening knives. I have only had to make a few passes with the fine ceramics and buckle on the belt. My experience is that it takes less than a minute to get hair-shaving razor-sharp from a working edge.

Field Testing


The Slim Pro 112 feather sticks well and the handle is well-shaped to do this job. It can throw sparks from Ferro rods, and the spine is strong. The handle also holds its edge well so you can move around from one task to another without having to pay attention to it.

Feathering works well with hardwoods such as cherry and oak.

These are not the most beautiful curls in oak and cherry.

These materials are feather-stickable.

These and black locusts are the most common materials that I can find in my wooded area.

These beautiful pines are easy to reach and don’t shed many branches.

Pine curls beautifully and requires very little effort.

The spine can also make kindling from fatwood or sticks, curling up small particles of fuzz and creating sparks that are easy to ignite.

Camp chores

The 112 Slim Pro is a great tool for camp. It cuts rope quickly and does a good job with any other cutting.

The slim blade and hollow grind make it easy to cook vegetables, meat, onions, and mushrooms. You can also use this tool to open tough plastic or cut ropes of any kind.

Here, S30V’s advantages are also evident.

I don’t have to worry about sharpening my knives for long trips. I also don’t have to care as much about drying and cleaning it. While I don’t advocate neglecting your knife, I have found that caring for it on canoe trips is a more or less constant chore.

Excellent edge retention and corrosion resistance are two things that I have learned to appreciate from the field. This is mostly because of my experience with knives with neither.

Cleaning fish

A spine is a good tool for removing scales.

This is the grip I use to cut from the cloaca down to the throat.

The sharp edge and fine point make it easy to make the required cuts. I also like the unique shape of 112 Slim Pro’s scales. It gives me a great place to rest my thumb, with the blade facing up.

Sharpness is important here. The sharper the blade, you have more control. This is always a good thing when you have a knife in one and a fish in the other.

The little knife is very efficient at processing bait and can be washed with warm water and soap. A quick rinse will remove any unpleasant odors.

Processing game

Game processing is an excellent test of edge retention. I have never been impressed with carbon steel used for this purpose.

My carbon knives and a few contacts with bone have required attention to regain the edge that would work the meat’s skin.

Buck’s S30V was a great choice, and my knife was sharp all the way. This performance isn’t possible with S30V, but my 440A or 420HC knives perform just as well.

Simple tasks were made easier by the fine point of the 112 Slim Pro than with the Mora 2000. Although the Mora is a great blade for many tasks, it was not sharp enough to make initial cuts on the legs. You may have different experiences, so it is entirely up to you.

You can make precise cuts thanks to the hollow grind and enhanced edge geometry.

The scales were still grippy when they were bloody, and perhaps as a final test, even after my hands had been greasy from handling sheepskin.

Even when I was cutting through joints, the lock remained in place. I used the tool exactly as it was intended. I didn’t twist the blade to free joints.

Last Thoughts

The 112 Slim Pro is the right knife for anglers and outdoorsmen?

That’s up to you.

A sturdy, compact, lightweight, and high-quality locking file is ideal for anyone who likes to hike, camp, fish, or hunt.
