墨付け（スミ付け）の二重チェックはもう不要です。HONGDUI HD38は、墨付け作業の迷いや推測を完全に排除する高効率なレイアウトツールです。堅牢なT型ショルダー（基准面）をワーク（加工材）の端面にピッタリとフラットにロックすることで、組み込まれたマイクロホールガイド（微小ガイド孔）を通じたシャープペンシルのスムーズな滑走を可能にし、シームレスで正確な平行線を引くことができます。ほぞ組み（榫卯構造）の墨付けから大判板材の割り出しまで、HD38は精度を倍増させながら作業時間を大幅に削減します。
* **高精度「ラインマスター」システム**：精密なスライディングブロックがしっかりと所定の位置にロックされ、ワークピースの長さに沿って完璧な平行ケガキと再現性の高いマーキングを実現します。
* **モジュラー式 2-in-1 設計**：T型ハンドルを取り外すことで、プロ仕様のT型スコヤから単体の高精度な直尺（ストレートエッジ）へと変形させることが可能です。
* **完璧な90度リファレンス**：ハンドル部分はCNC切削加工により、板の端に対して狂いのない正確な90度基準を確保し、従来のプレス加工された定規にありがちな誤差を完全に排除します。
* **円・弧の描画機能**：スライディングブロックに専用のピボットポイント（中心軸）を備えており、定規を大型のコンパスとして機能させ、正確な円や弧を描くことができます。
* **豊富なサイズ展開**：HD38シリーズは200mmから800mm（8インチ〜32インチ）までさまざまなサイズが用意されており、小型の家具部品から大型のパネルまで幅広く対応します。
* **アンチクリープ・ロッキング機構**：ローレット加工を施した真鍮製のロッキングナットにより、スライディングブロックをツール不要でしっかりと固定し、ケガキ作業中のズレを防止します。

FAQ
Check out the most common questions our customers asked.
What is the difference between the HD38 and the HD38V?
HD38 (Standard): Features a fixed 90-degree aluminum handle. It is designed for rock-solid right-angle layouts and parallel scribing.
HD38V (Adjustable): Features a rotating handle that allows for precision 0-90° angling. It includes a knurled brass knob for positive, drift-free locking at any angle, essentially acting as a high-precision protractor and T-square in one.
What is Hadfield Steel and why is it used for the ruler body?
Hadfield steel (manganese steel) is used for its superior toughness and shock resistance compared to standard spring steel. It has a hardness of approximately HRC 50 and is finished with a Titanium coating for extreme wear resistance, ensuring the ruler doesn't lose its straightness or surface quality over time.
What sizes are available?
The HD38 series is available in multiple lengths:
Metric: 200mm, 400mm, 600mm, and 800mm.
Imperial: 8 Inches, 16 Inches, 24 Inches, and 32 Inches.
What is the purpose of the Line Master sliders?
The Line Master is a modular sliding block that sits on the ruler. It allows for:
Repeatable Marking: Lock the slider at a specific measurement to mark the same distance on multiple workpieces.
Parallel Scribing: Press the slider against the edge of your board and slide the ruler to draw a perfectly parallel line.
Compass/Circle Drawing: The sliders can be used as pivot points for drawing large arcs and circles.
Why are there different colored sliders (Blue/Orange)?
Different colored sliders are often included in longer sets (600mm+) to help woodworkers distinguish between different presets or stops when performing complex layout tasks that require multiple measurements.
How accurate are the markings?
The HD38 features dual-scale laser-etched markings on both the front and back of the blade. This allows for clear readability even in awkward positions. The markings are mathematically aligned with the CNC-machined handle to ensure a perfect 90° reference.
Is the ruler handle removable?
Yes. The handle can be detached, allowing the Hadfield steel ruler to be used as a standalone straight edge or for layout tasks where the T-head would be in the way.
How do I calibrate the HD38V angle?
For the adjustable HD38V, you can use the laser-etched degree scale on the handle assembly. For critical accuracy, it is recommended to verify the 0° (90° to the handle) and 45° settings with a high-precision engineer's square during your initial setup.
Does the titanium coating protect against rust?
Yes, the titanium coating is highly resistant to corrosion. However, it is still best practice to wipe the ruler down with a dry cloth after use. If you work in a high-humidity environment, a light application of camellia oil or a dry wax will provide extra protection for the exposed steel edges.
How do I clean the Line Master sliders?
If the sliders become gritty or difficult to move, it is likely due to fine sawdust trapped in the track. Remove the slider, blow out the track with compressed air, and wipe the ruler's edge with a bit of denatured alcohol. Avoid using oil on the ruler body, as it will attract more dust.
