Shipping Policy

Any customers with separate shipping and billing addresses are subject to follow up contact. If no contact can be made, your order will be cancelled. Please understand that this policy is to protect our customers from fraud and theft.

Shipping costs are calculated automatically when you checkout. Orders to P.O. Boxes or military addresses require shipping via USPS.

Orders placed by 3:00pm EST will be shipped the same day. All orders shipped USPS (including Express) may take an additional business day to process and ship. We strongly recommend shipping UPS if you need guaranteed delivery by a certain date.

For our international customers, you must call or email after ordering to arrange for duties/customs and declarations before we will ship your order. USPS Express International shipments with declarations greater than $200, incur an additional $15.00 fee for postage/insurance.


By placing an order the buyer represents that he or she is of legal age and that the products ordered will be used in a lawful manner. We assume no responsibility for any harm or injury resulting from the sale, trade, use or handling of any product purchased from us. It is the responsibility of the buyer, not the seller, to ascertain and obey all applicable local, state, federal and international laws in regard to the possession, and or use, of any item purchased. We are unable to provide refunds in the event that the package that you have ordered was seized by customs or other agencies. Consult your local and state laws before ordering if you are in doubt.

Layaway Information

Layaway Policies

We offer a layaway plan on select products so you may pay for your order over a period of 60 days. Products that are eligible for layaway will show "Layaway Available: Yes" on the product page.

Here's how it works:

The total amount of the order excluding shipping, tax, or fees is divided into three (3) equal payments. The first payment is due with the order, the second payment is due 30 days later, and the final payment is due 60 days after the order.

There is a $15 non-refundable fee for layaway orders. This fee is added to the first payment along with the shipping and any tax. The first payment is made when the order is placed.

Example: Your order total is $300 plus $12.75 shipping and handling. If you select the layaway option, your payments would be:

  • $127.75 (1/3 of purchase = $100 + $15 layaway fee + $12.75 shipping)
  • $100.00 (1/3 of purchase = $100)
  • $100.00 (1/3 of purchase = $100)

If your initial payment is made by credit card, we will automatically process the 2nd and 3rd payments at the appropriate time using the same credit card information. You will be reminded via email that a payment will be charged. If you need to change this for any reason, please contact us.

For payments made other than credit card, payment must be received within seven (7) days of the due date or the order is subject to cancellation. You will receive a reminder via email that a payment is due.

If you wish to complete payment early and have your order shipped, you may contact us at any time during the 60 day period. There is no penalty for prepayment.

Additional products may be added to a layaway order without penalty. A new payment schedule will be calculated based on when additional products are added.

If you wish to complete payment early and have your order shipped, you may contact us at any time during the 60 day period. There is no penalty for early payment.

Cancellations of layaway orders are subject to a restocking/processing fee of 10% of the order total (not including tax and shipping costs). This restocking fee is in addition to the $15 non-refundable layaway fee.

Home Products Do Know Harm


The Kramer Custom Knives Do Know Harm was created based on the requirements of a currently practicing 18D trained combat and trauma medical doctor. Based off of an 11B scalpel blade and designed primarily as a medical tool, it also excels in defensive as well as EDC applications. The Do Know Harm can be called upon whenever you need precision work to be done. Its thin wharncliffe blade with acute point and two sets of jimping allow for unparalleled control. With a full grip the knife pierces and cuts aggressively beyond its relatively small footprint. A textured and contoured G10 handle affords most grip styles for the task at hand. Forward jimping allows control while climbing far forward on the knife for delicate work. The darkened AEB-L steel is able to hold a razor edge with a thin spine. Combined with its tactile G10 slabs, the Do Know Harm has a remarkably thin footprint.

The Kramer Custom Knives Do Know Harm carries securely in its fold over Kydex sheath. Quick to deploy, the sheath has high retention and adjustable carry positions due to the Ulti-Clip. Like every Kramer Custom Knife, the Do Know Harm is guaranteed against breakage. Whether for work or everyday carry, the Do Know Harm adaptability makes it a reliable ally.

A centerline spear point, dark wash AEB-L blade with acute tip for piercing and dual jimped thumb ramp for further leverage and choking up on the blade
