Simply use the allen key to replace the blade with the creaser or vice-versa. By loosening the bolster you can adjust the spacer arm or remove it altogether.
Why clutter your work space with excess tools? This versatile tool, with its adjustable and removable spacer arm and blade / creasing edge, allows you to press directly on the cutting / creasing edge giving you less slips and a more consistent groove or crease compared to standard groovers and creasers.
Made of high quality wood and steel, this outstanding tool will give you years of use.
