I think it's one of the best folding knives made, and a helluva deal at its price. It's light, thin, versatile in carry options, carries well, cuts well, is generally easy to maintain, and it can take a lot of hard (practically abusive) usage that most knives in that price point cannot.
I personally prefer the VG-10 versions with the standard saber grinds, but every Delica ever made has been great, and both the saber and flat grinds are of excellent quality.
The standard VG-10 steel is tough as nails, easy to sharpen, and gives good overall performance. The upgraded steels historically used have given a big boost edge retention/wear resistance, and are excellent performer at cutting abrasive materials like cardboard and certain rope/fiber that tends to quickly dull knives, but sometimes at the expense of lesser toughness, lesser corrosion resistance, and more difficulty in sharpening, so these are a great match for some users and terrible for others, depending upon usage and preferences. The upgraded steels also increase price a good bit. So a ZDP-189 or SuperBlue Delica may be great for you, or the standard VG-10 model may be as well.
