This a heck of a lot of knife for the money. 5160 Tool steel is terrific stuff. The shape of the knife is great. The flat grind is great. Great handle, great coating. Excellent length. So what's wrong? The edge was suitable for a hardware store shovel. It was about 45degrees. Luckily, I have a Burr King belt grinder. In about twenty minutes, I had it "Screaming Sharp". This is the way it should have come to me. My Ontario Raider Bowie came pretty sharp right out of the box. With a few licks of a steel, it shaved. Now this knife is so sharp it keeps me awake at night. If it had been sharp, I would have given it five stars. As it is, it still gets four stars. The sheath is two stars. It's OK for the door pocket of my truck but won't be worn.

I ordered the SP50 because I wanted a big, tough, heavy duty blade for chopping and splitting wood for fires and shelter building. The SP50 has done everything I have asked for it and holds an edge very well. The handle is very comfortable and fits my big hands like it was made for them and is very grippy. The only drawback I find with the SP50 is the cheap sheath that came with it. The sheath looks fairly good, but thats where it ends. A knife this size needs a dangler type sheath so it swings out of the way when you sit down - this one doesn't. Then the liner looks like its made from something they dug out of the trash - just some cheap clear plastic that appears to be heated and wrapped around a form and then cool in place and its very thin. One could remove it and replace it with some heat formed PVC pipe for a liner, but I decided to make a custom leather dangler type sheath that works much better than the original. Kudos on the SP50, but shame on the sheath !

The knife is much lighter than you would think given its size. It's actually a daily carry knife. Going shopping, walking around town and doing house work this thing is on my hip. It takes work to forget its there, but I often do. It's Sharp, but no razor by far. Faint tool marks are visible on the edge. But its a working knife not a straight razor.
Overall the sheath is well made and I find the plastic no trouble being lose as it does make up for having two button snaps if you want to speed pull the knife. It is a woods craft blade, but has great ability as a fighting knife. It's long, wide and thick enough to be used with force with no huge chunk taken from speed if you know how to use momentum and string cuts and thrusts together. Just like people who carry full size 1911 daily you have to see the advantages and work on making disadvantages not matter.
I give the knife and 8/10 but the company only a 6/10. It took 20 days from order date to get the knife. That is 7 days longer than any knife I have ever ordered. I would have been okay with the wait had I been made aware of it. After 2 calls and two emails I got no response. I had to call Ontario and only got a shipping status email a week after they made a call to the knife store. 15 days with no contact is a worry these days.
The knife is WELL worth $80 shipped.

First off new this year,the sheath has two Velcro/snap fasteners instead of the one plain Velcro fastener of years past. Great improvement on the sheath. The blade itself feels very light in the hand for its size. Excellent protective coding on the blade and a great grip. Cuts, hacks, delimbs,and holds an edge exceptionally well. You won't be disappointed.

The SP50 may be the best backpacking knife I have ever used. As a backpacker, a blade of this size will be used, primarily, for firewood processing. To that, the SP50 is tops. The SP50 draws a direct comparison to the exceptionally valued Ka-Bar Heavy Bowie. Both have Kraton handles, blades of the same length and blade bellies of the same size. Where the SP50 surpasses the KaBar, is in blade thickness and design. The SP50 has less taper and eliminates the false edge along the top. The result is a blade with more hacking ability [for de-limbing] and better wood splitting. Where the Ka Bar has an overall longer handle, the SP50 actually offers more grip length, as the butt is not nearly as thick.
Many enjoy the TNP You-Tube Channel…as do I. Where I part from his view is primarily on sheaths. I like the nylon sheath of Ontario. I appreciate the pocket provided to store fire-kits, multi-tools, fishing kits, sharpeners, flash lights, etc. The sheath holds the knife securely when fastened and allows for easy extraction and return when unfastens. This is a welcome feature when using the knife repeatedly.
The SP50 is the GLOCK of wood processing knives. Simple, form & function…without unnecessary frills-- Just a great knife.

The knife is a great design. The grip fits well in the hand. I have used this around my house cutting palm fronds, and some 2" wide trees. I bought this knife to put in my B.O.B. The sheath needs a little work. You need to remove the plastic insert and heat it with a heatgun to make the knife sung. I actually heated it too much and called the company up for a replacement. I offered to pay for it but they said that I would have to buy an entire new sheath. I didn't want to pay $20 for a new sheath when all I needed was a $2 plastic insert. After a few days of working on the insert I have it the way it should have been. It has two button straps, it only needs one not two. The straps just have enough slack to button around the handle. If Ontario Knife Co. would address the sheath I would give this Five Stars.

First thing I did when I got this was find the biggest log in our firewood downstairs and batoned it. Went through seven inch diameter seasoned hardwood in three blows, knots and all. Blade is top notch, but the sheath required some customization and still isn't great. They have at least improved some of the issues with the sheath the knife was originally sold with,(snaps now instead of velcro on the retention straps) but they've created others (glued in thermoplastic liner so retention can't be adjusted). Still, what do you want for this price?! I can't believe how good the blade is for the money.
