Question: Is the handle aluminium or steel?
Document: These knives are terrific. VERY sharp, easy to handle, and do not weigh very much so one can use them for a long time without feeling like you have to put the knife down. I love the solid design as it is very easy to clean and I know that there is no food under the handle. The fact that they are stainless steel is a plus. And the price is fabulous...you get a great product for a great price. I only wash them by hand.
gave this as a gift to my brother along with a diamond steel.great everyday use. Wipe the steel peridicly with a wet cloth to remove 'knife dust&#34;
What can the I say the stainless steel look in my kinda thing. Plus these things are pretty freakin sharp so if you like to use your hands while you talk I suggest you set these down while cooking. Ive only had them a few days so I cant say anything yet about longer term. Ill update my post if anything changes.
Best knives for the price. Easy to handle. Keep them sharp and they will cut through any type of food item
Very sharp!! nice comfortable handle. Light weight, makes my prep time faster and I can eat sooner. Great for all my vegetables. Easy to clean. I LOVE These. Highly Recommend.
The smooth finish and the rounded corners of the knife handle made the knife twist in my hand. Now that I am aware of the potential problem I can prevent any accidents, but the knife could get hard to control with slippery hands.
I purchased this set two months ago for its good reviews and very decent pricing.Both knives have good sharpness for this price. The handle was not forged with the razor. The smaller one started to show minor rust on the side of knife which is disappointing.
I have used many brands of knives including Chicago cutlery and I have to say that these Ginsu knives are as good or better than the more expensive brands. The shape and sharpness of the blade is very user friendly. The heft of the solid metal handle feels balanced when using it and truly gives it a comfortable feel.
Solid quality construction.Lifetime manufacturer warranty (send the knife + $3 for shipping to get replacement) - details included.Thin blades, great for slicing.Arrive sharp & ready to use.Heavy handle, well balanced in the hand.Classy, slightly modern look.Great knives for the price.
These Ginsu knives are a tremendous value. I recently was given a similar performing single knife with a better handle, but it costs $50! Here are two great knives for $20.00. They are extremely sharp, and the hollowed blade design reduces the tendency for cut items to stick on the blade. The set of smaller and larger versions is all you need to do most cutting jobs in the kitchen.
Answer: Steel its heavy
