I have been working intensively for many years in the professional model with editors. For precise curved cuts it is imperative that the blade is forward fixed wobble-free. This Cutter here has to my knowledge the only possibility the blade forward to fix without a screw or significant thickening in the front (visual and gripping) area. Only a blade change is somewhat tricky, I suppose but willing to accept. For this I can recommend the way the blades of Lutz.
