I can vouch for the Spainish cutlerers being of good working quality. I did much research before purchasing a holow handled survival knife, mainly because they get a bad rap when compared to the stronger full-tanged blade...I didnt want to end up with one that would bust in half as I am told they are prone to doing. The Esparcia caught my eye right off...not just the crossbow, but the blade had a bit of wickedness to the shape.
It did not pass my final inspection for 2 reasons:
1) I could not find a physical example of it to examine (wich is very important to me, I have a good eye for quality but the hands tell me much more)
2)The crossbow seemed cool (if not a bit gimick-ish) but not as practical as say a slingshot for it requires speacial ammo that is particularly easy to lose in a vegetated environment.
There were also a couple of shots that were unflattering of it on the internet. But to hold one is important before you buy. I finally decided on the Aitor Jungle King 2 but when I found it in person it felt like it was made of plastic, then the shopkeeper thrust the Jungle king 1 into my hand, and whoa! felt like I could cut the world in half with it. Ended up waiting to save an extra 100 bucks and got the JK1. Same thing happed when I was looking for a kick-around fixed blade. I had KABAR in in one hand, feeling the weight n balace and the guy put a Muela Mirage in my other hand (a knife wouldnt have even asked to see just because the look didnt catch me) and it was twice the knife the KABAR was and was the same price, bout 50 bucks. Muela is also a Spainish brand and it is a great knife, espeacially for the price.
