Two Little Fishies Bone Cutter
Top PickA staple reef tool for snapping and trimming SPS branches, birdsnest, and small stony coral skeletons. It is widely used by hobbyists who need dependable cutting power without moving into expensive surgical tools.
Pros
- +Cuts most small to medium SPS branches cleanly
- +Comfortable spring-loaded action for repeated frag sessions
- +Commonly available through reef retailers
Cons
- -Not ideal for soft corals or mushroom propagation
- -Can crush very thick acro bases if overloaded
Tunze Coral Cutter
A heavy-duty cutter designed for larger stony corals and tougher skeletons where lighter bone cutters struggle. It is well suited for reefers working with mature colonies and frequent propagation.
Pros
- +Excellent leverage for thicker SPS and LPS skeletons
- +Durable construction holds up well over time
- +Produces more controlled breaks on dense branches
Cons
- -More expensive than entry-level cutters
- -Less useful for detailed soft coral work
Coral Fragging Scalpel with Replaceable Blades
A surgical-style scalpel is one of the best tools for precision cuts on zoanthids, mushrooms, leather corals, and tissue separation work. It offers far more control than cutters when dealing with delicate flesh and small attachment points.
Pros
- +Excellent precision for soft corals and zoa mat cutting
- +Replaceable sterile blades reduce contamination risk
- +Very inexpensive to maintain
Cons
- -Not suitable for cutting thick stony skeletons
- -Requires careful handling for safety
Brightwell Razor Coral Fragging Kit
A multi-tool style fragging kit that gives hobbyists blades, cutters, and accessories for handling several coral types. It is especially useful for reef keepers who want one package for occasional fragging sessions.
Pros
- +Includes multiple tools for mixed coral propagation
- +Useful for zoanthids, soft corals, and some LPS work
- +Good starter value compared with buying each tool separately
Cons
- -Individual tools are not always as robust as specialty options
- -Blades may need replacing quickly with frequent use
Dremel Rotary Tool with Diamond Wheel
A Dremel-style rotary tool is popular for cutting thick LPS skeletons, encrusted frags, and large SPS bases with more control than manual snapping. It is especially useful when preserving tissue around difficult cut lines matters.
Pros
- +Handles thick skeletons that defeat standard cutters
- +Can make cleaner planned cuts on expensive colonies
- +Useful for frag plug and rack modifications too
Cons
- -Generates heat and debris if used carelessly
- -Requires more setup and confidence than hand tools
Coral RX Pro Fragging and Dip Workflow
While not a cutting tool itself, Coral RX Pro is a well-known companion option for fragging sessions because fresh frags often need pest inspection and dipping before mounting or trading. It adds an important layer of biosecurity for mixed reef and fish-heavy systems.
Pros
- +Helps reduce risk of introducing common coral pests
- +Useful before selling, trading, or moving frags between systems
- +Works well as part of a repeatable fragging routine
Cons
- -Does not replace proper quarantine practices
- -Not every coral tolerates the same dip exposure equally
The Verdict
For most reef hobbyists, a quality bone cutter plus a scalpel covers the majority of coral fragging jobs at a reasonable cost. If you work with thick SPS or LPS skeletons, step up to a Tunze cutter or Dremel, while beginners with mixed coral tanks often get the best value from an all-in-one fragging kit paired with a trusted coral dip workflow.
Pro Tips
- *Match the tool to the coral structure - bone cutters for branching SPS, scalpels for soft corals, and rotary tools for thick skeletons
- *Sterilize tools between colonies to reduce the risk of bacterial spread, brown jelly transfer, or pest contamination
- *Frag corals in stable water conditions, ideally with salinity around 1.025 SG, alkalinity 8-9 dKH, and temperature 76-78 F
- *Keep iodine or coral dip on hand for post-cut care, especially when trading frags between systems
- *If fish share the system, use a separate frag container or rack so curious wrasses, angels, and tangs do not stress fresh cuts
