Toothed or wavy? On a professional hand dispenser, the blade decides how cleanly the tape is cut. There is a dedicated blade shape for filament tape, while the second blade names no specific tape type. This comparison shows how the toothed and the wavy replacement blade differ and which dispenser suits which tape. You will find the dispensers in the professional hand dispensers category.

A dedicated blade for filament tape
For filament adhesive tapes, the manufacturer offers a dedicated wavy replacement blade. The product data do not say which property of the tape calls for this blade shape. What is stated is the assignment: wavy for filament adhesive tapes.
The toothed blade does not refer to any specific tape type in its name. It is described in general terms as a replacement blade for professional tape dispensers for 50 mm. If you use filament tape, the wavy blade is the version explicitly named for it. For other tapes, the toothed blade is an option, as no tape type is specified for it.
Which blade shape gives the cleaner cut in a particular case also depends on the tape you use. The best approach is to try it with your own tape before ordering larger quantities.
The matching hand dispensers
Our range includes two professional hand dispensers with the same basic data: outer diameter 136 mm, maximum roll width 50 mm, roll core 76 mm and a weight of 0.625 kg.
- General professional hand dispenser: the Professional hand dispenser red with unwind brake, 50mm tape width, 136mm outer diameter (designation T30R/50 AB) is intended for single-sided tapes according to its description. It has a one-piece metal frame, a hardened steel blade, an ergonomic handle, an unwind brake and an open tape locator.
- For filament tapes: the Professional hand dispenser for filament adhesive tapes red with unwind brake, 50mm tape width, 136mm outer diameter (designation T30R/50 AB WB) also has a metal frame, an ergonomic handle and an open tape locator. According to the manufacturer, the unwind brake sits on the core holder.
The product data do not explicitly state which blade each dispenser is fitted with at the factory. Nor is there a clear assignment of the replacement blades to these two dispensers. When reordering, pay attention to the blade shape and check the fit on the product page.
Replace the blade instead of the dispenser
The replacement blades are sold separately. This lets you swap the blade without replacing the whole dispenser:
- Choose the blade shape according to your tape: replacement blade for the professional tape dispenser, 50 mm, toothed or replacement blade for the professional tape dispenser for filament adhesive tapes, 50 mm, wavy.
- Change the blade following the manufacturer's instructions. The product data mention easy fitting, but no individual steps.
A change is also worthwhile when you switch tape types, for example from standard tape to filament tape.
Typical applications
Shipping with standard tape
At the shipping station in the warehouse, boxes are usually sealed with standard tape. The general professional hand dispenser, intended for single-sided tapes according to its description, is a good fit here. As a replacement, the toothed blade without a specific tape type is an option – check the fit on the product page. A stock of spare blades keeps the station ready for use.
Heavy boxes with filament tape
Where filament tape is used in production or workshop shipping, for example for heavy boxes or bundles, there is the hand dispenser for filament tapes and the wavy replacement blade.
Frequently asked questions
Can I also use the wavy blade for standard tape?
The product data explicitly name the wavy blade for filament adhesive tapes. The toothed blade names no specific tape type. The data do not say whether the wavy blade also cuts standard tape cleanly – if in doubt, try it out.
Will the replacement blades fit my dispenser?
According to the manufacturer, both blades are intended for professional tape dispensers for 50 mm and carry the designation T30R/50. Please check the fit with your dispenser on the product page.
