NT CutterHeavy Duty Chemical Resistant Poly Grip Multi-Blade Cartridge Knife, 1 Knife (L-700RP)

Well-built tool that is just handy to have around the house. I always make sure I know where it's at as it has come in handy so many times. Easy to reload with easy to get blades.

Exceptional build and design. The snap blades make for little waste (small fraction of using a typical box cutter with double sided razor blades). Additionally, you can select nearly as long a blade as you want. There is a lock screw to hold the blade in place once open, or prevent it from being opened. The handle ergonomics are very comfortable and secure in use. The handle holds 6 replacement blades (each having 8 blades - just snap off the dull section with the included plastic snapper or use a pair of pliers) for a total of 48 cutter blades before you need to "reload".A little pricey, but worth every penny.

These are the best retractable cutters you can buy. There is a reason you can find these everywhere in Japan, they are very well made. I read the review of the blade being blocked by the thumb screw. The screw unscrews out of the housing but it is a left hand thread meaning left to tighten and right to loosen. I have been using this one for a month and it is a great cutter. I am including photos to show the back and how it works.

It feels solid in my hand. The blade auto-load feature is nice. The black material on the shell is actually hard plastic, not rubber as I thought; but it still gives good grip though. The ratchet slider moves a bit too smooth. I would prefer it to have a more defined click at each notch, but it's just my preference.

Took a little long to arrive from Japan, but when it finally did, I was quite impressed with the NT Cutter. It is by far the best blade cutter I've ever owned. It has several unique features for holding spare blades, blade tightening, and is very well made. High quality materials insure a likelihood of many years of trouble free use. Couldn't be happier.

The best utility knife I've ever owned... and I'm an architect... I've gone through many of these in my career. I've typically used the aluminum version of this, but I like that the plastic body is much lighter.

Blades are already rusting

As it looks, functional, sturdy not too big and not too small - perfect for most projects

このタイプは、裏に、予備の刃が何枚か入るからか、刃を、出すときに、少し指に力が要ります

アルミボディは価格が倍ほどになりますがこれで十分👍

グリップがしっくりします。刃を格納すると、そこそこ重くなります。

The media could not be loaded.  手持ちのカッター全てプラのロック機構の部分が壊れて使い物にならなかったので、プロの電工さんがオススメしていたこれを購入してみました。動画では刃の交換や折るのを実践してみました。※動画や画像内のオルファの刃は手持ちの別のカッターから取り外したものです。◯良い点・オルファの替刃との互換性あり→もちろん切れ味は刃に依存します。・肉厚で持ちやすい・6枚入るので予備の入れ物を別途持たなくて済む・ロック機構が金属ネジ式で丈夫なので劣化して壊れなそう▲気になった点・6連発ではありますが、刃は購入当初は2枚しか入っていない→え？　6枚入ってると思って買ったのは自分だけ？　注意不足と思い込みですねｗ・刃を折る赤い三角形が有用ではなかった→使ってみたら変な所から折れてしまう（動画参照）。　やり方がまずかったのかもしれませんが、個人的には刃を折るのは付属の物を使うよりも普通にペンチで折ったほうが安全かつ正確に折れますね。使い勝手は明らかに前の安物カッターよりいいので、満足しています。

思っより、早く届きました。早速使用しました。良かったです♪
