Punches • Fullers • Chisels - Use & Care…
ABOUT YOUR TOOL
Water Oak Forge struck tools are hand-forged from 5/8" O1 tool steel or 4140 (Drifts) and designed specifically for hot work. Use only on material at an appropriate forging temperature for the alloy being worked.
Do not use these tools to punch, cut, pierce, or create impressions in cold, hardened, or heat-treated steel. Light texturing or repoussé work on mild sheet metal may be possible but is not their intended purpose.
Only the working ends of straight and curved chisels and center punches are heat treated. Punches, fullers, and decorative tools are supplied in their normalized condition. This is intentional: normalized O1 provides excellent durability for hot work while remaining more forgiving and easily maintained if deformation occurs..
Struck tools are consumable working tools. Normal wear and periodic dressing should be expected. Proper use, cooling, and maintenance can provide many years of service.
BEFORE EACH USE
Inspect the tool before every use. Check the working and struck ends for cracks, chips, mushrooming, burrs, or deformation.
Dress minor wear before it becomes excessive. If a crack or significant chip is present, discontinue use immediately.
Always wear appropriate PPE. Eye protection and suitable protective clothing are essential. Gloves, an apron, hearing protection, and other PPE should be used as appropriate for the operation.
USING YOUR TOOL
Use these tools only against material at an appropriate hot-forging temperature. Heat transfers rapidly from the workpiece into the tool, especially through small working ends.
PLACE • STRIKE • REMOVE • ASSESS • COOL • REPEAT
Avoid holding the tool against hot material while delivering an extended series of blows. Remove it frequently to assess your work and control heat buildup.
PUNCHING THROUGH
When punching completely through material, always provide clearance beneath the work using an appropriate hardy hole, pritchel block, or bolster block.
Never punch through directly against the face of your anvil. Contact between the punch and anvil can damage both the tool and anvil face.
HEAT MANAGEMENT
Keep your tool cool. Cool frequently using a slower quenching oil or an organic alternative such as peanut oil. The working end may also be wiped across a lightly oil-soaked rag between strikes.
If the entire tool becomes too warm to comfortably handle, stop and allow it to cool in still air or, provided no visible heat is present, cool it in oil.
If the tool shows any visible heat or color, remove it from service and allow it to cool naturally in still air until all visible color is gone before further cooling. Never quench a visibly hot tool in oil.
Wipe excess oil from the tool before returning it to the workpiece to reduce smoke and flare-ups.
MAINTENANCE & DRESSING
Normal wear, mushrooming, and minor deformation can occur during use and should be addressed as part of routine tool maintenance.
Working End: Remove burrs, sharp edges, and deformation with a file or grinder, returning the tool as closely as practical to its original geometry.
Struck End: Dress mushrooming, rolled edges, and minor deformation before they become excessive. Maintain a clean, properly shaped striking surface.
GRINDING & HEAT CONTROL
When grinding, use light pressure and short passes. Do not continuously hold the tool against a grinding wheel or belt.
Keep the tool cool enough to comfortably handle with a bare hand. If it becomes too hot to hold, stop grinding and allow it to cool naturally before continuing.
Take particular care when dressing the heat-treated ends of chisels and center punches. Do not allow these areas to develop visible heat or temper colors, as excessive heat can alter their heat treatment.
Never attempt to compensate for overheating by rapidly quenching the tool.
CRACKS = STOP
If a crack is visible anywhere on the tool, discontinue use immediately. Do not weld, repair, grind out, or continue using a cracked struck tool.
SAFETY & ASSUMPTION OF RISK
Blacksmithing is inherently hazardous. Hot steel may exceed 1,500°F, and forging involves open flame, sparks, scale, spall, metal slugs, hammers, struck tools, and other hazards capable of causing serious injury, burns, property damage, or death.
Scale, slugs, and metal fragments may fall or travel unexpectedly during punching, cutting, fullering, and other forging operations. Maintain a safe work area, keep others clear, and always use appropriate PPE.
The user is responsible for selecting the appropriate tool, inspecting and maintaining it, following its intended-use limitations, using appropriate PPE, and maintaining a safe working environment.
By participating in blacksmithing activities and using these tools, the user acknowledges and assumes all risks associated with blacksmithing and the use of struck tools.
This guide provides general use, care, and maintenance recommendations only and cannot address every application, technique, working condition, or hazard. It is not a substitute for proper training, experience, sound judgment, or established shop safety practices.
Never use a tool that is cracked, significantly damaged, improperly maintained, or used outside its intended purpose.
