The little piece of ruler on the vertical slider not only keeps it vertical, but also provide a guide for doing parallel and offset cuts.
The Perfect Cut
‘The Perfect Cut’ is a set of desktop tools that allows inexperienced users to perform precise cuts on various sheet materials like cardboard, foam core, leather, and cloth.
It assists the users to control the angle and depth of the cut, in cases of cutting circles and splines freehanded and along straight edges. There are snap-off blades, scalpels, rotary cutters, two sliders, circle cutter tools, and rulers in the set. With different combinations of the parts, ‘The Perfect Cut’ not only performs all kinds of impeccable cuts, but also saves time on practicing and redoing.
The Perfect Cut 是一組多功能美工刀，目的是讓初學者也能輕易的處理模型製作中常用的有厚度的材料，並切出完美的斷面，進而省去大量的練習與失誤。
The Perfect Cut 由八種不同的單元所組成，包括 30 度美工刀、手術刀、滾刀、角
度調節滑塊、曲線切割輔助器、切圓器、圓心墊、尺。
30度美工刀與手術刀可裝在角度調節滑塊上，進行 45~90 度之間的切割，其中美工刀更可以調節下刀的深度。特製的尺除了底部有防滑軟木墊之外，頭尾更有卡榫可使其相接以延長切割範圍。
角度調節滑塊並可接上切圓器使用，可以切割半徑 3~20 公分的圓，並可配合圓心墊，使切圓器圓心處的針尖不致傷到材料。圓心墊另有垂直規的功能，可連接兩把尺後提供 90 度參考。
三種美工刀都可裝在曲線切割輔助器上。曲線切割輔助器主要功能為徒手切曲線時可使刀片與材料表面垂直，並可調節下刀深度。曲線切割輔助器上的輔助尺另提供平行線的參考，大幅節省繪製參考線的時間。
The Perfect Cut 之所有模組都可依左右手切換，讓使用者有 100% 的順暢體驗
