Steel rail | Cutter + safety knife in 1 | Cutting depth up to 76 mm
The Tajima QuickBack 2 in 1 is a cutter knife with an 18 mm snap-off blade of safety level 1 with automatic blade retraction in safety mode. This is made possible by an additional spring-loaded second slider that retracts the blade automatically when it is fully pulled back – in normal cutter knife operation, by contrast, it can be locked in place as usual.
The housing is made of high-quality glass-fibre-filled plastic with soft-grip zones, reinforced by a steel rail in the blade channel that withstands even prying and turning work. The particularly ergonomic design with a large, smooth-running slider sits securely in the hand, and the Japanese carbon steel blade impresses with high initial sharpness – the knife is therefore designed for intensive use of more than 1,000 cuts per day.
The slider is designed exclusively for right-handed users. The cutting depth of up to 76 mm can be adjusted, and the blade is changed without tools directly at the workstation. The narrow housing opening guides the blade precisely, and despite the steel rail the knife remains handy at 121 g compared with other steel-rail cutter knives.
The QuickBack 2 in 1 is suitable for broad use in trades and production – from adhesive tape and cartons to strapping –, but is especially popular with exhibition stand builders looking for a sturdy, versatile cutter knife with an additional safety option. Safety knives overview
Which materials is this knife made for — and where does it reach its limits?
The integrated tape scorer opens adhesive tape reliably, without having to use the main blade for it.
Cartons can be opened by cutting off lids and flaps or with a precise window cut – the adjustable cutting depth protects the contents.
The sturdy snap-off blade cuts strapping reliably, and the stable steel rail holds up even under tension.
Not every safety knife is built the same – and you only notice it when it matters in everyday use. In the knife know-how section we show you at a glance how the QuickBack 2 in 1 performs in the most important respects: from the safety mechanism and grip quality to blade performance. This lets you judge whether it suits your application. If you have questions about choosing, we are happy to help you personally.
Automatic blade retraction — the blade retracts by itself as soon as you release the handle, no need to push it back manually.

Download →The QuickBack 2 in 1 is supplied with a K041 (black snap-off blade, Japanese carbon steel). The knife is compatible with standard 18 mm snap-off blades from various manufacturers – for example K041O, K043O (without snap-off segments, for polystyrene) or the Martor blade KM79. Our recommendation for everyday use remains the supplied K041. Overview of all snap-off blades

View KLWBThe QuickBack 2 in 1 occupies a niche between cutter knife and safety knife. If you prefer a classic cutter knife with manual blade retraction, you will find it in the C061. The Martor Secubase 383 follows a similar hybrid principle, but locks the blade in fixed positions instead of using a second slider. If you want a pure safety knife with a long blade instead, you will find it in the US11 or in the Tortoris S21 with adjustable cutting depth.
