Good knife
This knife is sturdier than some other knives that I bought, so far. I like a folding knife with blade storage. I work retail and go through a lot of blades, so it's nice to have some on hand. Hopefully it lasts longer than other knives I've had.

Quality Tool
As advertised. This is a heavy-duty tool. I expect it to last a very long time. Mine is a must-have for opening packages and cutting boxes down for the trash can. This one is a lot heavier than I expected and the curved shape has a great feel.

Good Knife but not so Great Blade Compartment
This knife came with blades. The knife itself seems pretty well built and very sturdy when it is unfolded. The clip on the knife is also very sturdy. I have been using mine for months now. The blades are also very easy to change in and out. The only complaint I have is that blade compartment button is very sensitive. If it gets a slight bump, the blade compartment will fling open and all my extra blades will fall out.It is a great knife for the price!

Great utility knife
I've tried a lot of different utility knives, but this one is the best. Easy to use and change blades. Also there is a little storage area in the knife for the extra blades when needed.

Sturdy!
This is the sturdiest folding utility knife I’ve owned. I use them all the time for work cutting tubing, drywall, etc and this thing is sturdy. Blade locks in tight unlike other brands I’ve bought on here. It came in a plastic sealed package like a good knife bought at a store verses loose in a cardboard box. The extra blade storage is a nice feature. Pocket clip is nice and tight as well. It’s a quality utility knife, and I’m very pleased with the purchase!

Good All Around Utility Knife, Few Faults, But No Standout Features Either
At $11.99 (at the time of this review) this utility knife by B Sosi Tools is priced in the middle of the pack for folding utility knives on Amazon. This is a good all around knife with solid construction, storage for 5 blades and a relatively deep carry pocket clip. For some reason the item description on Amazon says "utility knife with wooden handle", but the handle is actually some kind of lightweight metal. No wood at all on this knife ... It's comfortable in the hand, but for me some additional contours on the handle would increase grip. I like the yellow color, as it's more visible on a jobsite. The only real issue I have with this knife is that I find it difficult to open, two hands are required and the area on the silver blade extension to be pinched to open the knife is very smooth and difficult to get a grip on. This area really should have some texture or be a bit bigger to aid in the opening process.Other than the less than easy opening procedure there's little wrong with this knife. In the end this is a good, maybe even a very good knife, in a straightforward, no fuss kind of way. That's both its strength and weakness, as this straightforward, no fuss knife that has very few faults also has no standout features to get me excited about. It's a utility knife with blade storage that's a bit difficult to open -- that's about it. If that's what you're looking for this isn't a bad option at all.

Easy to use - built to last
I'm happy with this cutter. It feels solid, has a nice storage area for spare blades, it's easy to open, easy to change blades and seems built to last.

Great utility knife. Holds 3 extra blades, and you can extend the blade out 3 lengths.
The media could not be loaded. There are a few things that I really like about this utility knife. #1 the blade can be extended out and locked at .25”, .62” or fully extended at 1 inch. For opening boxes, which mainly involves cutting only packing tape, there’s no need to extend the blade out past the .25” length, but if you need to, it’s a simple press and push of the button. #2 there are three extra blades stored securely in the handle. They are easy to access and switching out the blades is simple. Obviously you’ll want to use BOTH ends of each blade before you put an entirely new blade in. #3 the angle of the handle is more ergonomic than a straight handled knife. If you use a utility knife for an extended period, you’ll definitely appreciate the angled grip. # the yellow color stands out and is easy to see when the knife is in a tool box, tool bag or under the seat of my truck. Those black, gray and other dark colored knives seem to disappear at the bottom of a toolbox. # the switch requires you to press is down then forward to extend the blade or down and back to retract the blade. This is a safety feature that most other utility knives don’t have. I think it’s a great design and I like it. It doesn’t take any longer to use than any other utility knife, and if it does, the safety makes it work it.I hope this review was helpful.Thank you.
