Personally, I love Persians. I EDC C83 every day for more than three years. I carry C105 on weekends, along with C83. I used to have original Stretch, but never warm up to this blade and sold it.
But it is me.
Stretch and 75 mm Persian are quite different blades. All depends on your needs and preferences. C105 is classy gents knife. Great ergos, great cutting tool, probably will satisfy 95% needs of average person. Also looks great. Made by Moki, so fit and finish are outstanding. Action is little tight at the beginning, but after a little while will be smooth. The knife is discontinued, but most of the large on-line dealers still have it. IMHO C105 Persian more suite for office or dress-up environment. You do not want to beat-up this knife.
Stretch has full flat grind 3.5" blade, great ergos. Good EDC, if 3" blade feels too short. Can take quite a beating.
