How to Find a Chipped Stone (Sharp Flint Flake) in Project Zomboid
Build 42.19 · Vanilla Stones forage + Knapping · No mods required
Short answer
In Build 42.19 the English display name is Sharp Flint Flake. Older guides still call it “chipped stone.” You can forage it outdoors in the Stones category, or craft it with Knap Sharp Flint Flake: one Flint Nodule plus a kept stone hammer, mallet, or Knapping Tool. No skill gate and no mod is required for that knap recipe.

What the item is now
- Display name: Sharp Flint Flake (older guides: “chipped stone”)
- Weight: 1.0 · has condition (max 5)
- Role: knapping ingredient and a usable sharp-knife tool for recipes that accept that tool type — not only a craft material
- Related stock: Flint Nodule tooltip states it is used for knapping and can be broken into a Sharp Flint Flake
Two vanilla ways to get it
1. Forage outdoors (Stones category)
- Enter search / investigate mode on outdoor ground (right-click the ground → investigate / search for this area, same foraging UI as other materials).
- Focus on the Stones category when the focus list is available. There is no high Foraging level gate just to see Stones.
- Pick up the icon when it appears; it goes into inventory like other forage finds. Foraging XP for each flake is low.
Sharp Flint Flake and Flint Nodule both appear in the same zone set: forest variants, farmland, vegetation, town, trailer park, and road / navigation strips (ForagingNav). They are not limited to “forests outside the city.”
| Zone (Stones category weight) | Relative weight | Practical note |
|---|---|---|
| Roads / nav (ForagingNav) | 120 | Highest Stones weight — often better than deep forest for stone rolls |
| Vegetation | 30 | Strong outdoor strip option near edges and scrub |
| PHForest / PRForest | 25 | Pine / maple-style forest variants beat generic forest weight |
| Town / Trailer Park | 15 | Urban and trailer lots still roll Stones; not forest-only |
| Forest / Deep Forest / Farmland / Organic & Birch forest | 10 | Valid, but lower category weight than roads and vegetation |
Once you are focused on Stones, Sharp Flint Flake and Flint Nodule share the same per-zone chance across those areas. Snow heavily reduces finds. Light, distance, and traits still apply — see the foraging guide.
2. Craft: Knap Sharp Flint Flake (vanilla)
Mods are not required
In Build 42.19, Knap Sharp Flint Flake is a vanilla knapping recipe: no Workshop mod, no magazine unlock, and no skill requirement. Foraging is optional if you already have a Flint Nodule and a valid tool.
- Get one Flint Nodule (forage Stones the same way, or loot where flint materials appear).
- Keep a stone hammer, wooden mallet, or Knapping Tool in inventory. The tool is kept and may take light condition damage.
- Open the craft menu → Knapping → Knap Sharp Flint Flake (works on any surface). Output: one Sharp Flint Flake plus a small amount of Knapping XP.
Traits and occupations that actually help
Park Ranger, Hiker, and Hunter improve general vision / weather / darkness for foraging. They do not add a Stones specialisation. For Stones category bonus specifically:
| Trait / occupation | Stones specialisation | Other relevant effect |
|---|---|---|
| Mason (trait) | +30 | Best dedicated Stones focus in current forage skill defs |
| Wilderness Knowledge (trait) | +5 | Also small bonuses to plants, animals, firewood, and mild vision |
| Park Ranger / Hiker / Hunter | none | Vision and weather help you see finds, not a Stones roll bonus |

Real uses for Sharp Flint Flake
The flake is a knapping and assembly ingredient, not a general building material for walls or floors. Stone Hammer is assembled from ordinary stone plus a branch and bindings — the head is not Sharp Flint Flake.
| Recipe (EN) | Output | Skill / learn | Other inputs (summary) |
|---|---|---|---|
| Knap Stone Awl | Awl - Stone | Must learn; auto-learn Knapping 2 | 1 flake + keep stone hammer / mallet / knapping tool |
| Make Crude Stone Axe | Crude Stone Axe | Maintenance 1; no recipe book gate | Tree branch, flake as head, 2 simple weapon bindings |
| Knap Stone Blade | Stone Blade | Knapping 1; must learn; auto-learn Knapping 3 | 1 flake + keep knapping tool |
| Knap Stone Blade Scythe | Stone-Blade Scythe | Knapping 2; must learn; auto-learn Knapping 5 | Tree branch or handle + flake + tool |
| Knap Stone Chisel | Stone Chisel | Knapping 1; must learn; auto-learn Knapping 4 | 2 flakes + tool |
| Knapp Flint Saw | Flint Saw | Knapping 3; must learn; auto-learn Knapping 6 | Branch/handle, flake, twine or leather strips, tool |
| Knap Stone Drill | Stone Drill | Knapping 5; must learn; auto-learn Knapping 8 | 1 flake + hammer/mallet/knapping tool + crude or mason chisel |
- Long Stone Blade is knapped from a Flint Nodule at Knapping 6, not from an existing flake.
- Large axe / maul heads use Flat Stone, not Sharp Flint Flake.
- You can research Stone Blade and Stone Awl recipes by studying a finished flake in-game when that research option is available.
- Because the flake counts as a sharp knife tool, it can also stand in for the knife step on some assembly recipes (for example Stone Hammer) until its condition is spent — that is tool use, not a dedicated “craft spearhead from chipped stone” recipe.
Practical tips
- Prefer roads / navigation strips and vegetation edges when hunting Stones, not only deep forest loops.
- Forage both flakes and nodules: nodules convert to flakes with any valid knapping tool, so one good tool multiplies your supply.
- Take Mason if your run is built around stone materials; otherwise lean on vision traits and more search time.
- Snow and darkness make finds harder — clear weather and daylight still matter even with category focus.
- Plan flake sinks: two flakes per Stone Chisel, one per blade / awl / crude axe head, higher Knapping for saw and drill.
Numbers at a glance
- Display name: Sharp Flint Flake (legacy search: chipped stone)
- Weight / condition: 1.0 · max condition 5
- Knap recipe: 1× Flint Nodule + kept hammer/mallet/knapping tool → 1× flake; no skill gate
- Best Stones zones: roads/nav (120) > vegetation (30) > PH/PR forest (25) > town/trailer (15) > generic forest/farm (10)
- Stones trait bonus: Mason +30 · Wilderness Knowledge +5
