Monster Hunter Sharpness Calculator

Sharpness is one of the most important weapon stats in the Monster Hunter series. It determines how much of your raw (physical) damage and elemental damage actually lands on the monster. Every time your weapon strikes a target, it consumes sharpness units. When those units run out, the weapon drops to the next lower sharpness level — reducing your damage output significantly until you sharpen it back up.

The sharpness gauge is divided into seven colour-coded tiers: Red, Orange, Yellow, Green, Blue, White, and Purple. Each tier applies a fixed multiplier to your raw damage and a separate multiplier to your elemental damage. Maintaining the highest possible sharpness level throughout a hunt is therefore a central part of Monster Hunter's combat loop — choosing the right maintenance skills and understanding how quickly your weapon degrades directly affects your effective DPS.

This Monster Hunter Sharpness Calculator helps you model all of those factors in one place. Enter your weapon's base sharpness units, your Handicraft skill level, and any sharpness-preservation skills like Razor Sharp or Master's Touch, and the calculator tells you exactly how many effective hits you get before the next sharpen and how much DPS time you lose to the sharpening animation.

Each sharpness colour applies a multiplier to your final raw damage and elemental damage. The table below lists the exact multipliers used by this calculator:

The jump from Yellow (1.00) to Blue (1.20) is a full 20% raw damage increase — the largest single-tier gain in the entire chart. The final step from White (1.32) to Purple (1.39) adds about 5.3% more raw and a further 6.7% to elemental. Maintaining Purple sharpness on weapons that can reach it is generally the strongest option for endgame content.

The Handicraft skill extends your weapon's sharpness gauge, adding 10 sharpness units per skill level up to a maximum of level 5. That means Handicraft 5 gives +50 effective sharpness units, which can push a weapon into the next colour tier if it only needs a small boost.

However, Handicraft only adds units — it cannot create a colour tier that doesn't exist on the weapon's internal sharpness bar. If a weapon has no white sharpness in its base gauge, Handicraft will not add white sharpness no matter how many levels you run. In this calculator, the Handicraft bonus is applied directly to the entered sharpness units, letting you simulate the total effective pool at your chosen tier.

Deciding how many Handicraft levels to run involves a trade-off. Each skill slot given to Handicraft competes with offensive gems like Attack Boost or Critical Eye. A common approach is to run exactly the number of Handicraft levels needed to reach the next sharpness colour tier and no more, then fill remaining slots with raw or affinity skills. Use this calculator to find that threshold and make an informed decision for your build.

Beyond Handicraft, Monster Hunter offers several skills that reduce the rate at which your weapon loses sharpness:

• Razor Sharp / Spare Shot — Gives a 50% chance that a hit does not consume sharpness. In practice this doubles the expected number of effective hits from a given sharpness pool. In the calculator, enabling Razor Sharp multiplies the sharpness multiplier by 2.
• Master's Touch — Critical hits do not consume sharpness at all. At high affinity values this is extremely powerful. The calculator computes the multiplier as 1 / (1 − affinity%). At 80% affinity that is 1 / 0.20 = 5×, meaning you effectively get five times as many hits from your sharpness pool. At 100% affinity sharpness never depletes while Master's Touch is active.
• Protective Polish — After sharpening, sharpness does not deplete for a fixed duration (60 seconds at level 1, 90 seconds at levels 2 and 3). This skill is most effective on speedrunners or hunters who plan their sharpening windows around monster openings.

Razor Sharp and Master's Touch can be combined. When both are active the multipliers stack multiplicatively. At 80% affinity and Razor Sharp the combined multiplier is 2 × 5 = 10, giving ten times the raw sharpness hits — effectively eliminating almost all sharpening downtime in a normal hunt.

The right combination depends on your weapon's natural sharpness pool, your crit build's affinity, and how long your hunts typically last. This sharpness calculator models each combination so you can compare total uptime numbers side by side before committing to a build.

Speed Sharpening reduces the number of whetstone cycles required when sharpening your weapon. At level 0 the animation takes 4 cycles × 0.8 seconds = 3.2 seconds. Each skill level removes one cycle, so Speed Sharpening 3 (the maximum) brings the animation down to 1 cycle × 0.8 seconds = 0.8 seconds — a 75% reduction in sharpening downtime.

DPS loss from sharpening is calculated by comparing total sharpen time to total combat window time. The formula the calculator uses is:

DPS Loss (%) = totalSharpenTime / (hitsPerSharpen × 0.5 + totalSharpenTime) × 100

Where totalSharpenTime = sharpensNeeded × sharpenTime and sharpensNeeded = ceil(hitsPerSharpen / effectiveHits). The factor of 0.5 seconds per hit represents an assumed average time between hits. Even a modest reduction in sharpening animation time through Speed Sharpening 3 can meaningfully lower your DPS loss percentage, particularly for weapons that drain sharpness quickly like Dual Blades or Charge Blade in SAED mode.

For most builds that already run Razor Sharp or Master's Touch, Speed Sharpening provides marginal benefit because sharpening events are already rare. Its value is highest on weapons with low base sharpness or on builds that cannot slot in the heavier preservation skills.
