Thanks for the heads up! What is difference between the 2 models?
Both material and cutting strength are the same.
The difference between them is the spring material & handle color.
SP-23 is using metal spring & SP-33 is using plastic spring.
SP-23 seems to have a better spring strength then SP-33 because it's using metal spring.
But for SP-33, the plastic type of spring design is quite unique also and it's actually removable which is good for people who don't like having a spring.
Both models are pretty worth it in terms of price over quality ratio and furthermore is really made in Japan. Definitely can on par or even win those overpriced "branded" ones which most ppl are using nowadays.. Just chose 1 and you won't disappointed.
Anyway market nowadays for tools mostly is made in China or Taiwan which quality really not there.. Try a real Japanese tool and feel the difference! Haha..
Anyway went to Gundam Expo took a look and enquired that a set of markers is ard $20.75, individual marker (only grey) is $3.15, and nipper or cutter they called it for $13? I called Ekon hardware, and was told there are several types like dunno how many mm, and need to go down have a look.
