Question: Does this knife come with a blade guard or do I need to purchase one?
Document: I can get thinner slices than I can with my electric knife. Quite sharp. I suggest you purchase the Messermeister 12&#34; Edge Guard because the knife does not come with a blade guard.
I bought this knife for the sole purpose of carving flank steak. It worked perfectly. Very sharp. Very little flex in the blade. Paper thin slices. Great value for the price. You will need to fashion a sheath for drawer storage as it does not come with one. I used the rigid plastic it came shipped in. Works fine.
I chose to get this to cut larger cuts of meat such as London Broils, cutting larger cuts of Steak, Roasts and such.Rather than using an electric knife which tend not to last or work to well. Very Sharp and feels great in the hand with a non slip handle. Very Comfortable. Keep in mind this knife does NOT come with a blade cover. Do yourself a favor and dont purchase the Messermeister blade cover that comes up as recommended with this purchase.
This knife is easy to use and enables me to get nice thin slices from my roasts. Wish it came with a blade guard, but I think I can order one separately. This is a nice all around knife, long enough at 12" to slice through just about any piece of meat, but not so long I'm poking through to the other size of the meat board! It's a nice mid-range price and quality, and I love the granton edge.
I use this knife to slice beef brisket when I am competing in BBQ competitions. I need those slices to be absolutely perfect. No saw marks, completely equal and uniform, and no tearouts. This knife is unbelievably sharp and the length allows me to do a slice in one long pull. The hollows in the blade keep the meat from 'sticking' to the blade and messing up the cut. I love this knife and it was money very well spent.
Great knife and exactly what I have been looking for without spending an enormous amount of money. Will purchase again if need be.
I used this knife several times on roasts and would buy it again. I am able to slice paper thin slices that is great for sandwiches. I was considering purchasing an electric slicer before I made this purchase, I don't see the need anymore .. I gave this 4 stars because I can't compare it to any similar knifes
This knife cut through a good size prime rib with little effort. I have used much more expensive knives that did not perform any better. I wish it had come with a sheath. I would have been willing to pay more to get one with the knife.
I own numerous Victorinox knives and have never been dissapointed with a purchase, and with this one nothing has changed that view. Faster and easier than any electric carving knife, gives you the total control factor. Thick or thin is easy to do, easily cleaned, no drop cords etc. perfect for meats. Highly recommend.
It is a big knife with no teeth, I did not think it is sharp, it looks like a 12 inches ruler. Well, knife is a knife especially with such a big name VICTORINOX. I searched my home for a bread, not easy, finally  found one in the corner of my refrigerator. The bread is only 5 inches long, but I can cut it several pieces with very thin layers. I am very happy with this purchase.
