Can I get a court-appointed lawyer for knife laws in Kansas?
Kansas's rule on court-appointed lawyers: A defendant who claims to be unable to afford counsel files an affidavit in the form set by the State Board of Indigents' Defense Services; the court may question the defendant under oath and investigate finances. The court considers the defendant's assets and income, necessary expenses for the defendant and immediate family, the anticipated cost of effective representation by employed counsel, and property transferred without adequate consideration after the alleged crime. If the defendant cannot cover the anticipated cost, the defendant is determined indigent in full or in part and counsel is appointed. The determination may be reviewed at any time. A defendant applying for appointed counsel must pay an application fee of $100 to the clerk of the district court, which the court may waive in whole or in part.

What happens after an arrest for knife laws in Kansas?
How release before trial works in Kansas: A person charged with a crime shall be released at the first appearance before a magistrate on an appearance bond sufficient to assure appearance and public safety. Bonds may be surety bonds (with sufficient solvent Kansas-resident sureties), cash deposits, or own-recognizance bonds; for bonds of $2,500 or less on certain lower-level offenses a 10% cash deposit may be allowed if listed qualifications are met. Conditions can include no contact with the alleged victim for at least 72 hours in person-crime cases, custody with a designated person, travel or association limits, house arrest and court services supervision. In setting the bond the magistrate considers the nature and circumstances of the crime, the weight of the evidence, whether the defendant is lawfully present in the United States, family ties, employment, finances, character, mental condition, length of residence, criminal record, appearance history, the likelihood of new crimes or threats to victims or witnesses, and whether the defendant was on probation or parole. A detained person may apply for review of release conditions, which must occur without unnecessary delay. Defendants charged with sex offenses who have a prior sexually violent crime conviction must have a bond of at least $750,000.
