I ordered one recently from a local brick and mortar store but didn't take it home due to fit and finish issues.
The blade rubbed the liner pretty badly and the very tip of the blade was not a straight edge but curved down suddenly and would have made sharpening difficult, it also exhibited gap in the liners and a back spring that wasn't flush.
Didn't expect a perfect knife for the price but this example was unacceptable.
The spring was quite strong similar to a douk douk but a little grittier.
It did come with a very nice plastic snap box that was finished better than the knife, and the wood handle was quite nice as well.
Would still like to buy one, but wouldn't order one sight unseen.
Aitor has several other intriguing folders that resemble sod busters, very good prices on those.
