This time, I think I got some wrong decisions to buy them. But why? I would tell you gradually.
OLFA CK-1 (the consumable is CKB-1) Craft knife
Extruded metal body with matting black spray, its high productive quality make attractions. And it's slim but I could say it's easier to control than its looks.
The most important is it's cheap~
簡單用中文寫些感想好了，壓鑄的金屬本體和消光黑噴漆，由於製作工藝品質極好，所以還挺迷人的，雖然薄，但是還算好控制，重點是便宜（以OLFA的產品來說）
OLFA Ltd-06 Stainless Steel Blade Craft Knife (Limit CK)
Similar to CK-1, this model have thick plastic body. Ya, it's not the metal body, but the plastic body is firm. So, although I would prefer the wood or metal body's temperature and weight, this still provide satisfying touch and handle.
Its blade is made with stainless steel, have 30 degree angle. Shape and Expansive.
類似 CK-1，只是刀片是不鏽鋼，角度變成30度，雖然質感和握感俱佳，可惜是塑膠本體，有些缺憾也有些貴。
OLFA Ltd-07L Limited NL
This is a SHIT! Designed as a seamless length control make this unsafe and dangerous to use, you would never know when the lock screw would be loosen and the blade will cut anyone. The shiny plastic body and grip could not compensate the defective and faulty safety design. Do not buy this, you would regret.
爛設計，不值得買！
BTW, this is my NT CUTTER-LG, made in Osaka, Japan. With firm aluminum body and anti-slide stopper on the front end. And the red blade picker is made as the warning. For safety reason, this is better.
反而這隻NT cutter-LG 安全穩定多了
OLFA Top Sheet Cutter 一枚切
An interesting and expensive product, it has the return pressure control and special cutting angle w/o the shape directly pressed on the paper, seems that could make you only cut the top sheet. HAHAHA, it's a wrong and cheat. You would never know how many force you could press. So its only advantage exists at when you are not a professional-tool user and you do not have suitable cutting pad under the sheet, you could pick other thicker paper such as A4 copy paper to instead of the cutting pad. OK, I regret again.
昂貴的唬人產品，如果已經有適當切割工具的話，可以不用看這隻，這只適合沒事會隨手整理折價券的日本人。
OLFA PRC-2 18mm Perforation Cutter (the consumables is PRB18)
Good! What can I say! When I need to cut a dot line, I have no choice to use it.
好用的東西，事實上根本沒得選擇。
OLFA PRC-3 28mm Perforation Cutter (the consumables is PRB28)
OK~if the PRC-2 could not satisfy the need, I have the bigger one.
大一點的也是有
OLFA CS-3(125B) (the consumables is SWB-3(XB-125))
An easy handled plastic and wood/bamboo saw. Still do not have chance to use this.
OLFA CMP-2 Snap-Off Blades Circle Cutter
I do not have this knife using experience before. but I know when I need to cut a circle up to 7~30cm diameters, it would be useful.
