Terms of Service
Last updated: August 3, 2026
Introduction
Welcome to KnotWorks (“we,” “our,” or “us”). These Terms of Service (“Terms”) govern your use of our website at allsplice.com and all associated rope and knot calculators, tools, and services (collectively, the “Service”).
By accessing or using our Service, you agree to be bound by these Terms. If you disagree with any part of these Terms, you may not access the Service.
Acceptance of Terms
By accessing, browsing, or using KnotWorks, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated herein by reference.
We reserve the right to update or modify these Terms at any time without prior notice. Your continued use of the Service after any such changes constitutes acceptance of the new Terms.
Informational Use & Verifying Results
KnotWorks provides estimates and tools for general craft guidance and informational purposes only. Calculator results and the guidance on the Service are informational and may be incomplete, approximate, or based on rule-of-thumb figures rather than a specific rope manufacturer’s specification. Rope construction, fiber, condition, and diameter all affect real-world results, and they vary by manufacturer and product. By using the Service you agree to treat results as general estimates rather than a guarantee, and to confirm any figure that matters — especially a working load limit — against the rope manufacturer’s published specification or a qualified rigging professional before you rely on it. Nothing on this site is a safety certification, engineering sign-off, or professional rigging advice.
Description of Service
KnotWorks provides free, practical calculators and educational resources, including:
- Rope length estimator
- Knot selector by use
- Working load limit guide (general guidance, not a safety certification)
- Paracord needed calculator
- Splice tuck counter
- Whipping length calculator, and educational content, guides, and best practices
All tools are provided free of charge. We reserve the right to modify, suspend, or discontinue any part of the Service at any time.
User Responsibilities
Appropriate Use
Users of our tools and website agree to:
- Use the tools in good faith for legitimate personal purposes
- Provide accurate figures when using our calculators
- Not attempt to disrupt or compromise the website’s functionality
- Not use automated systems to access our tools excessively
- Respect intellectual property rights
- Not use the tools for any illegal or unauthorised purpose
Your Own Judgment
You are responsible for your own knots, splices, and rigging decisions. Our tools are designed to assist and inform, not to replace your own judgment, proper training, or a rope manufacturer’s published specifications and instructions.
Tool Accuracy and Disclaimers
Calculation Accuracy
Our calculators are provided for informational and educational purposes only. While we strive for accuracy, we cannot guarantee that every calculation will be error-free or suitable for your specific situation. Results are estimates based on common craft and rigging conventions and the figures you enter; actual rope consumption, knot strength, and load capacity depend on the specific rope, knot, and conditions.
No Guarantee of Results
KnotWorks makes no warranties, expressed or implied, and disclaims all other warranties including implied warranties of merchantability, fitness for a particular purpose, or non-infringement.
Not a Safety Certification
The Working Load Limit Guide in particular is general educational arithmetic, not an inspection of your actual rope, an engineering sign-off, or a substitute for a rope manufacturer’s rated hardware and published specifications. Rope work, climbing, rigging, and load-bearing applications carry real risk, including the risk of serious injury. Never rely on this Service alone for overhead, life-safety, or load-bearing-on-a-person applications.
Intellectual Property Rights
All content on this website, including text, graphics, logos, tools, calculators, and software, is the property of KnotWorks or its content suppliers and is protected by applicable copyright laws. Museum and learn content sourced from Wikipedia and Wikimedia Commons remains under its respective public-domain or Creative Commons licenses.

Privacy and Data Protection
Your use of our website and tools is also governed by our Privacy Policy. All tool calculations happen in your browser and are not transmitted to us.
Limitation of Liability
In no event shall KnotWorks or its suppliers be liable for any damages (including, without limitation, damages for loss of data, personal injury, property damage, or other loss) arising out of the use or inability to use the materials or tools on KnotWorks, even if KnotWorks or an authorised representative has been notified of the possibility of such damage.
