Hi, I've had three or four Typhoons over the years and have always found the quality to be excellent, I think you may have just been very unlucky with yours. I also like them in particular because although a homage, Jake stamps his own design identity on them, he doesn't try to copy exactly. Also until fairly recently they were the only 6105 homage available apart from the discontinued and hard to find Smith's model.
I may be wrong, but I get a feeling regarding the seeming multitude of Chinese models available lately that these companies would be happy to make fakes but have found the homage market just as lucrative. There was one on sc the other day I enquired about at a hard to resist price. But it was sold almost instantly, so they must be doing something right.
