Question: How long are the blades?
Document: I have been looking for a knife with blades similar to these for a very long long time! I was soooo happy when I found these here on Amazon!They are super awesome!
Honestly! I bought these more for decoration than anything else and I'm still disappointing. The smaller knife isn't even 4 inches long. There is no reason to buy this unless you have a toddler that thinks knives are cool.
The pictures of them don't show how nice they really are and there is a flame on one side of the blades
My boyfriend likes them, I like them..the blades are pretty sharp, all in all a good buy.
this set of beautiful blades is just what I was looking for. they are beautiful and sharp. i appreciate the quality of this product.
These are beautiful blades. However, they're not very big at all. I was disappointed with the size, but not the craftsmanship or appearance otherwise.
All i can say about this product is wow, the detail is great i love everything about this item Blades are durable, not to sharp perfect for a scifi cosplayer. Will definitely be purchasing from this user in the future.
I bought these for my husband for Christmas & he absolutely loves them. Great quality sheath & blades are snugly fitted in it. Great buy for the price if you know someone who is a collector of different blades.
I got this for my boyfriend as one of his Christmas gifts, and he loves them. He really likes blades of all kinds, so this was definitely a win. I did think they would be a little bigger, but all in all I'm happy. Price was great too :)
I got this as an addon to another gift.Thought it was going to be 2 digger size blades, or at leas one big blade and a small one.All I got was a letter opener size single blade.
Answer: yes
