I just received a pair of knives that are in the "& Related Slipjoints" category, but I think the are very closely related. These are both Winchester brand knives, however they share many characteristics of Rough Rider knives, and I believe they are probably made by the same company.
They have excellent fit and finish.
This is a nicely executed standard swell-center whittler, with the main blade resting on the two springs. The springs do not have the "split back" divider, but the secondary blades do have a brass divider between them.
This is a really nice large toothpick- 4.25 inch blade from tip to handle. Winchester "Collector's Edition." I really like this one!
Here is the whittler with my EDC (Chinese Robert Klaas). You can see the handles are a lighter color yellow which is quite nice. It has a very well executed clip blade.
Honestly I have been waiting for a Chinese version of the Case Classic large toothpick for a long time! The Winchester is stainless while I'm fairly sure the Case Classic is not. The Winchester has a half stop, while the Case Classic does not. The Winchester has a higher, hollow grind while the Case Classic has a thicker saber grind. The Winchester cost considerably less than the Case Classic. I think I like the Winchester a bit better! I will certainly use it more while the Case Classic is going to rest in my collection.
Both are very nice. There is a large Winchester "Collector's Edition" whittler that has swedges everywhere that I've been eyeballing and am even more tempted to get soon after having handled the large toothpick knife of the series.
