  1. Brass back / spine

    Stiffens the thin plate during a straight joinery cut.

  2. Steel saw plate

    Carries the cutting teeth below the rigid back.

  3. Rip toothline

    15 ppi rip filing cuts along the grain for dovetails.

  4. Cherry open handle

    Gives a balanced grip and helps sight the cut.

  5. Brass split nuts

    Fasten the handle to the plate; use the fitting driver.

02 / Understand the tool

What it is and what each part does

A dovetail saw is a fine-toothed backsaw for short, accurate joinery cuts along the grain. The named Lie-Nielsen 1-SAW-DS has a stiff brass back, thin Swedish-steel plate, cherry open handle and 15-points-per-inch rip filing. Its 10-inch usable blade and 1⅝-inch depth limit the height of a through cut. A crosscut carcass saw uses different filing to sever fibers across the grain; a larger tenon saw has more capacity for deeper joinery.

The brass spine holds the thin plate rigid while the fine rip teeth remove a narrow kerf. Two split-nut bolts secure the wooden handle. Accuracy begins with the first few strokes: keep the plate registered beside the layout line, use the whole toothline with light pressure and let the saw's set provide clearance. The poster shows actual external groups, not a service sequence.

Brass back

The solid milled spine stiffens and adds weight to the thin blade, but also limits cutting depth. Do not twist the blade in a kerf.

Steel plate and set

The 1-SAW-DS uses a 0.020-inch plate with slight set. The maker quotes about 0.003 inch of set per side and a 0.026-inch kerf; this is model-specific, not a universal dovetail-saw value.

Rip teeth

Fifteen points per inch are filed for cuts running with the grain, as in dovetail tails and pins. A tooth close-up in the poster repeats this feature at larger scale.

Open handle and fasteners

The cherry grip is held by traditional brass split nuts. It gives directional control; a correctly fitting split-nut screwdriver is needed for fastener work.

02 / Working principle

Set, guide and control the action

These decisions make the mechanism useful at the bench.

Lay out the joint

Mark baseline and tails or pins with a knife or sharp pencil; identify the waste side before cutting. Hold the board upright and stable.

Start the kerf

Set the teeth beside the waste-side line, sight the blade across both faces and start slowly with little downward force. The model instructions recommend the plate flush with the stock top rather than a pronounced tilt.

Follow the line

Use long even strokes, keeping the blade upright and watching the near and far layout lines. Stop at the baseline; a small set makes late corrections difficult.

Through dovetails

Saw tail or pin cheeks to the baseline, then remove waste using a suitable coping saw and chisel or the planned method.

Small rip joinery

The fine rip teeth can cut short tenon cheeks and other shallow cuts within the saw's depth.

Practice cuts

Cut parallel kerfs in scrap to learn the saw's tracking and the line offset before cutting a fitted joint.

03 / At the bench

Setup, technique and finish quality

Use the steps for a first pass, then inspect the work before changing the setup.

  1. Secure and square the stock; mark a clear baseline on every relevant face and identify waste.
  2. Inspect the teeth and handle, then grip with the index finger extending along the back for guidance.
  3. Register the plate beside the waste-side line and begin slowly with minimal downward pressure.
  4. Saw with long even strokes, watching both the near and far line; do not twist a developing kerf.
  5. Stop at the baseline and remove remaining waste with a suitable method; test-fit without forcing the joint.
  6. Protect the teeth after use and keep the high-carbon plate dry.

Registration governs tracking

The very first kerf guides later strokes. A fine-set saw has little room for correction once off the line.

Pressure is not speed

The maker notes that grabbing or jumping is often too much downward pressure. Reduce pressure and use more of the toothline.

Cut on the correct side

Dovetail fitting depends on preserving the layout line. Decide which face is waste before bringing teeth to wood.

Depth has a limit

The spine eventually meets the work. Use a deeper backsaw or another method when the required cut exceeds this model's blade depth.

What changes by model or material

Rip versus crosscut filing

Rip filing suits dovetail cheek cuts with the grain. A crosscut carcass saw has a different tooth geometry for shoulder and across-grain work.

Open and closed handles

The grip shape changes comfort and fastener type; this reference has an open cherry handle and split nuts.

Tapered and straight backs

Some saws taper plate depth for a different sightline and balance. The selected 1-SAW-DS is the standard straight-back form.

Pitch and set

Finer teeth suit smaller work but can cut more slowly; tooth count, set and filing vary by maker. Use a matching sharpening method.

Choosing the tool

  • Match usable blade depth to stock thickness and dovetail size.
  • Compare rip filing, tooth pitch, plate thickness and handle fit in your hand.
  • Choose a saw that can be sharpened and whose tooth guard and maintenance needs fit the shop.

Useful accessories

  • Secure vise or dovetail vise
  • Marking knife, square and dovetail gauge
  • Coping saw and narrow chisel for waste removal
  • Tooth guard and correctly sized saw file

Consumables

  • Practice stock
  • Light rust protection for the steel plate
  • Saw files and sharpening supplies as needed
04 / Keep control

Care, troubleshooting and safety

Secure the work, protect sharp edges and release any stored clamping pressure before adjustment or maintenance.

Care checklist

  • Brush away sawdust, dry the plate and apply a light protective coat as the maker directs.
  • Store with teeth guarded; avoid bending or twisting the thin plate.
  • Inspect handle fasteners before use; use a fitting split-nut driver if adjustment is needed.
  • Have the fine rip teeth sharpened or learn the model's filing and set procedure before altering them.

Common mistakes

  • Starting on the kept side of the line.
  • Pushing so hard the teeth jump.
  • Twisting to correct an established kerf.
  • Running the back into stock deeper than the usable blade.

Safety at the operation

  • Clamp the work so both hands can control the cut.
  • Keep the supporting hand out of the tooth path and use a stable stance.
  • Fit a tooth guard when carrying or storing the saw.
  • Use appropriate eye protection when cutting or sharpening.

When the result goes wrong

Saw wanders

Recheck the first kerf, sighting on both faces, even pressure and tooth set; practice in scrap before altering the set.

Teeth grab or skip

Reduce downward pressure, check the stock is secure and inspect tooth sharpness.

Saw binds

Check blade twist, stock movement and whether the cut exceeds the spine-limited depth.
