Score Your Razor Hand Saw

What We’re Scoring On (Your “Dream Razor” Anchor)

We start by defining one perfect razor hand saw — our dream model. Every spec you enter gets compared to these ideal values. Each metric begins at 10 points and loses 1 point for each defined step it strays. Minimum score for any metric is 1 point.

• Blade length: 5.0 in
• TPI (teeth per inch): 32 TPI
• Kerf / thickness: 0.010 in (≈0.25 mm)
• Tooth hardening / type: Impulse hardened, fine teeth
• Blade material: Hardened high-carbon or branded Japanese steel

Note: This tool does not cover every possible specification. The formula used is only made to give a general idea of what a good product may look like. It’s a great way to shortlist your choices, but this tool is not 100% bias-free, and cannot replace real-world testing insights

Values for the Best Razor Hand Saw

Metric	Dream Spec	Score at Perfect Match
Blade length	5.0 in	10
TPI	32	10
Kerf / thickness	0.010 in	10
Tooth hardening / type	Impulse hardened, fine teeth	10
Blade material	Hardened high-carbon / Japanese steel	10

Enter any real-world spec and each metric starts at 10. The score drops by one point for each full step away from the dream spec, down to 1 point.

Score Changes Due to Deviation

Here is how each metric loses points as it deviates from the dream values.

Blade length

• Rule: Subtract 1 point for every 0.5 inch the blade length is away from 5.0 in. Minimum score is 1 point.
• Examples:
  • Exactly 5.0 in → 10 points
  • Within ±0.5 in (4.5–5.5 in) → 9 points
  • Within ±1.0 in (4.0–6.0 in) → 8 points
  • Within ±1.5 in (3.5–6.5 in) → 7 points
  • Within ±2.0 in (3.0–7.0 in) → 6 points
  • Within ±2.5 in (2.5–7.5 in) → 5 points
  • Continue dropping 1 point per 0.5 in band until the minimum of 1 point

TPI

• Rule: Subtract 1 point for every 4 TPI the value is away from 32 TPI. Minimum score is 1 point.
• Examples:
  • Exactly 32 TPI → 10 points
  • 28–31 or 33–36 → 9 points
  • 24–27 or 37–40 → 8 points
  • 20–23 or 41–44 → 7 points
  • 16–19 or 45–48 → 6 points
  • Continue dropping 1 point per 4 TPI band until the minimum of 1 point

Kerf / thickness

• Rule: Subtract 1 point for every 0.002 inch the kerf is away from 0.010 in. Minimum score is 1 point.
• Examples:
  • Exactly 0.010 in → 10 points
  • 0.008–0.0119 in → 9 points
  • 0.006–0.0139 in → 8 points
  • 0.004–0.0159 in → 7 points
  • 0.002–0.0179 in → 6 points
  • Continue dropping 1 point per 0.002 in band until the minimum of 1 point

Tooth hardening / type

• Impulse hardened, fine teeth → 10
• Hardened, generic fine teeth → 9
• Ground teeth, not hardened → 8
• Stamped, untreated teeth → 7
• If the spec sheet gives no info, give lower scores accordingly, never below 1

Each category step above reduces the score by 1 point from the ideal.

Blade material

• Hardened high-carbon or branded Japanese steel → 10
• Hardened stainless alloy → 9
• Tool or alloy steel with decent hardness → 8
• Generic high-carbon, quality unclear → 6
• Unknown or soft/budget alloy → 4

Each listed category is one step from the ideal. If the spec sheet names the steel or states “hardened,” choose the higher score.

How to Use

1. Open the Razor Hand Saw Spec Scorer tool on this page.
2. Enter the spec values from the product sheet: blade length, TPI, kerf, tooth hardening, and blade material.
3. Click Score Saw. Each metric will show a 1–10 score based on the rules above.
4. Read the overall score. The tool averages the five metric scores to produce a final rating from 1.0 to 10.0. Higher means closer to the Dream Razor.

Use this page to compare razor saws by their published specs. A higher score means the saw matches the dream razor hand saw used for precise hobby and model work.
