not good when it gets into the blade
350823
Really need to work on the locking in part...it just work on friction to keep the blade protector in...not good when it gets into the blade..It suppose to protect the blade. Should you want to pay me I can tell you how to fix it with no or little cost.

The edge of this scraper is not smooth. Grooves from the saw are evident. Manufacturing should have sanded this with fine grain sand paper to smooth the edges.  Having the grooves traps dirt, germs, etc. making this product not sanitary for kitchen use.

Don't like that I have to pull the blade out and it's hard to close if you don't know how.

Blade guard broke the day I got it. Can't stay open now, will close if I put too much pressure on the blade.

It does a very poor job and I hate it. I would not recommend it to anyone. After using it , it ruined the blade and I had to go purchase new blades!

Please be warned, as others have stated, this knife will cause more problems than its worth and really should be discontinued.
The simple fact that the blade will only stay in the knife handle if the knife is in the clumsy and not well designed "lock" position, alone is enough to toss this thing.

I spent WAY too long trying to get the blade fully inserted.  I jiggled and pushed, afraid I was going to cut myself.  I thought something must be jammed.  I checked out a youtube video to be sure I was doing it right.  Yep.  Finally I took it apart, nothing blocking anything.  It was a pain putting it back, more parts and trouble than the old fashioned box cutters.  After a few more tries, the blade finally locked in.  If it is this much trouble when I have to change rhe blade, I will throw it out.

The knife looks great but it is hardrer and harder to close it. I've oiled it several times but the blade release gets stuck in the open position.

Nice blade and the knife is good to hold. However, the blade is stiff to open . It took time for it to loosen up. The locking mechanism is very stiff and the Benchmade axis lock is clearly superior.

It only happens when the knife has a lot of pressure down on it that the lock goes past the blade and requires ANOTHER knife to open it. Solid knife, but I rarely use it since the lock locks itself to much.

It makes a dull knife sharper and it does pass the potato test.  It doesn't fare so well against tomatoes and copy paper.  What is more concerning is the reviews of the replacement blades, which point out how quickly they wear out.  I use this on my cheap steak knives that I don't mind subjecting to the abuse of the dishwasher.

This thing loves to grind metal off the blade like crazy. I originally suspected it of leaving chips and pits, though I can't actually confirm it does.  From what I can tell the damage was already there.  That said, keep this far away from bread knives with long teeth as it tends to knock down and bend the serrated points.  This is where I'd consider using an electric grinder.

Take heed from the 1-star reviews, don't buy this for your good knives.  It will wreck the edge on the blade and simply cannot get it sharp enough for most prep work or heavy duty use.

If the food doesnt get pressed into the blade, all the food at that bottom almost turns into a paste. Good for those who don't like chunky salsa, but Id prefer a couple different blades for different food.

After using it once, the blade already was misshapen. After using it a few more times, the blades don't even close completely.

The cuts on the blade are clean .  1. But  the blade is out of round.  2.  Cuts are only good for a few inches, then are blade wants to suck the tile in to the blade.  3.  any cut longer than 4 inches and the tile snaps.  Cant use it for  tile cutting at all

I bought this knife as a replacement for an aging folding lock blade I currently have. At first I liked it. Good tool steel in the blade, strong, not too long opened, nice point for piercing and serrated edge for heavy duty cutting of straps. After a week of moderate use (opening and closing for cutting insulation, rope, packing straps, drywall and ceiling tiles) I found that the blade started opening in my pocket. After the second day of opening in my pocket (only once each day, I had thought I didn't re-seat the blade well enough and it was opening due to my negligence) It opened 4 times, cutting through my pants pocket and finally the back of my hand as I reached into the pocket for keys. I no longer carry this knife and it has been relegated to the tool bench where it won't be carried. I feel the design is unsafe and needs a blade lock to keep the blade from opening. I would not recommend this knife to anyone who intended to carry it in a pocket or waistband.

It is a good blade at the start.  But after several board feet of book match cuts on 6" soft maple, I can feel that it does not want to cut anymore.  It is still good for 3/4" cuts, but book matching -- not.  I would go with carbide tipped and probably narrower than 3/4" to get less friction and save the time and hassle to replace blades.

Update:  Do not buy this blade if you want long-term value for the money.  Cost per foot of cut, wood slicer or similar high quality blade is worth the money.  It costs more, but you are getting a lot more from the blade.  This Grizzly blade wears out very quickly, and cuts wavy lines uncontrollably. But once changed to a wood slicer, it straightens out and cuts effortlessly.  Don't waste your money and time on this blade.  Not sure why anyone would buy this, other than, like me, they didn't know any better at the start.

The tightening screw losens while cutting and ruins the blade edge. I bought one replaced it and now I have a useles $80 shear because the warranty expired.
