Question: How long is the blade?
Document: I bought this as a Christmas present for my boyfriend, who loves all things Celtic. It's a nice knife, and he's going to love it! It is heavy and sturdy. Seems sharp (though I haven't tested it). It came in a box with a sheath around the blade.
I bought this just to add to a collection. It seems well made. Blade doesn't wobble and feels really nice in the hand. Decently sharp and cool looking. I like Celtic stuff. If you are looking for a $100.00 knife for this price, its not for you. Good knife overall.
I was very excited about this knife but sadly opening the box I was very let down. The handle is square and not rounded as appears by shadowing on picture. The blade itself was dirty with film. The background of the designs are not black but a darker shade of grey then the pattern. I canceled my other orders of similar blades from this company.
So this knife is pretty cheap first of all, and although I haven't used it extensively the construction seems very solid.Blade:  Blade is much longer than I expected based on the picture, but hey, whatever. The blade isn't very sharp out of the box so that's a negative, but it was pretty easy to sharpen up to a more acceptable level.Ergonomics:  The knife feels kinda... dusty? Is the best way to put it I think.
if you were expecting a heavy (flat ) knife  that does  not forms well with the hand this for you. Not well balanced but looks good from a far distance.
didn't have the funds to purchase
Very nice especially for the price, cool store fun to look at all of their different and unique and interesting items
Very elegant and comfortable knife. This goes very well with my Renaissance Costuming. I've been offered up to $100. but, NOPE, I ain't selling !! !
This knife arrived quickly and is very handsome. I am certain that my son, who is a collector will enjoy it completely!
The handle, while it looks rounded in this picture is more square in nature, but it fits my hand perfectly. Some people might not like the fact that it lacks jimping but it can be added if you've got the tools. It's on the heavy side but that's to be expected.Other notes:  Wish the background for the knot-work was darker but you can still see it pretty well, green wood looks pretty good.
Answer: yes
