“KERF”是使用 FontVibe AI 创作的激光切割文字效果。粗壮无衬线大写字母从暖色桦木上激光切出，切口边缘焦黑、木纹清晰，凸立在深色胡桃木板上，琥珀色侧光。

Create a square laser-cut maker-studio logo presentation for the exact word "KERF". The wordmark is the entire hero, centered and spanning 76% of the canvas width. Use custom-built industrial stencil display lettering: bold uniform strokes, compact proportions, angular diagonal shear-cut terminals, tight but readable spacing. Make the R counter a real laser-cut opening retained with one narrow horizontal bridge tab; show the tab clearly as part of the mark. Fabricate each letter as a 7 mm dark walnut plywood slab, not printed typography and not CGI extrusion. Faces show fine straight walnut grain with a dry matte oil finish. Every perimeter is a mathematically precise laser kerf: a thin charcoal-black char seam around every cut boundary, crisp vertical cross-grain cut faces, real slab thickness visible along the lower-right edges. Place the walnut wordmark on a flush pale birch plywood backing panel; all negative spaces are actual cut-through openings revealing the birch beneath. Use a clean square composition with generous empty birch field around the wordmark. Low-left 15-degree amber raking sidelight catches the walnut face grain and exposes narrow, sharply defined rightward shadow lines beneath each slab and bridge gap. The outer field falls into a dark warm-brown timber-workshop surface at the frame edges. Add only a faint engraved square registration notch in the lower-right corner of the birch backing as a fabrication detail; no additional text, icons, gradients, outlines, glow, drop shadows, screws, tools, or decorative objects. Straight-on near-flat-lay camera, precise material photography, sharp kerf detail.
